Related Devices Part No. AD5601/AD5611/AD5621 Description 2.7 V to 5.5 V, <100 A, 8-, 10-, 12-bit nanoDAC with SPI(R) interface in tiny LFCSP and SC70 packages GENERAL DESCRIPTION The AD5602/AD5612/AD5622, members of the nanoDAC family, are single 8-, 10-, 12-bit buffered voltage-out DACs that operate from a single 2.7 V to 5.5 V supply, consuming <100 A at 5 V. These DACs come in tiny LFCSP and SC70 packages. Each DAC contains an on-chip precision output amplifier that allows rail-to-rail output swing to be achieved. The AD5602/AD5612/AD5622 use a 2-wire I2C-compatible serial interface that operates in standard (100 kHz), fast (400 kHz), and high speed (3.4 MHz) modes. The references for AD5602/AD5612/AD5622 are derived from the power supply inputs to give the widest dynamic output range. Each part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place to the device. The parts contain a power-down feature that reduces the current consumption of the devices to <150 nA at 3 V and provides software-selectable output loads while in power-down mode. The parts are put into power-down mode over the serial interface. The low power consumption of the AD5602/AD5612/AD5622 in normal operation makes them ideally suited for use in portable battery-operated equipment. The typical power consumption is 0.4 mW at 5 V. PRODUCT HIGHLIGHTS 1. Available in 6-lead LFCSP and SC70 packages. 2. Maximum 100 A power consumption, single-supply operation. These parts operate from a single 2.7 V to 5.5 V supply, typically consuming 0.2 mW at 3 V and 0.4 mW at 5 V, making them ideal for battery-powered applications. 3. The on-chip output buffer amplifier allows the output of the DAC to swing rail-to-rail with a typical slew rate of 0.5 V/s. 4. Reference derived from the power supply. 5. Standard, fast, and high speed mode I2C interface. 6. Designed for very low power consumption. 7. Power-down capability. When powered down, the DAC typically consumes <150 nA at 3 V. 8. Power-on reset and brownout detection. Rev. C Information furnished by Analog Devices is believed to be accurate and reliable.

High speed mode timing specification applies to the AD5602-1/AD5612-1/AD5622-1 only. Standard and fast mode timing specifications apply to the AD5602-1/AD5612-1/AD5622-1 and AD5602-2/AD5612-2/AD5622-2. 2 CB refers to the capacitance on the bus line. 3 The SDA and SCL timing is measured with the input filters enabled. Switching off the input filters improves the transfer rate but has a negative effect on EMC behavior of the part. 4 Input filtering on the SCL and SDA inputs suppress noise spikes that are less than 50 ns for fast mode or 10 ns for high speed mode. 1 TIMING DIAGRAM t11 t12 t6 t2 SCL t1 t6 t4 t5 t8 t10 t3 t9 t7 P S S Figure 2. 2-Wire Serial Interface Timing Diagram Rev.

A typical INL vs. code plot can be seen in Figure 5. Differential Nonlinearity (DNL) Differential nonlinearity is the difference between the measured change and the ideal 1 LSB change between any two adjacent codes. A specified differential nonlinearity of 1 LSB maximum ensures monotonicity. This DAC is guaranteed monotonic by design. A typical DNL vs. code plot can be seen in Figure 6. Zero Code Error Zero-code error is due to a combination of the offset errors in the DAC and output amplifier; it is a measure of the output error when zero code (0x0000) is loaded to the DAC register. Ideally, the output should be 0 V. The zero-code error is always positive in the AD5602/AD5612/AD5622 because the output of the DAC cannot go below 0 V. Zero-code error is expressed in mV. A plot of zero-code error vs. temperature can be seen in Figure 18. Full-Scale Error Full-scale error is a measure of the output error when full-scale code (0xFFFF) is loaded to the DAC register; it is expressed in percent of full-scale range. Ideally, the output should be VDD - 1 LSB. A plot of full-scale error vs. temperature can be seen in Figure 18. Gain Error Gain error is a measure of the span error of the DAC. It is the deviation in slope of the DAC transfer characteristic from ideal expressed as a percent of the full-scale range. Total Unadjusted Error (TUE) Total unadjusted error is a measure of the output error taking all the various errors into account. A typical TUE vs. code plot can be seen in Figure 11. Zero Code Error Drift Zero code error drift is a measure of the change in zero code error with a change in temperature. It is expressed in V/C. Gain Error Drift Gain error drift is a measure of the change in gain error with changes in temperature. It is expressed in (ppm of full-scale range)/C. Digital-to-Analog Glitch Impulse Digital-to-analog glitch impulse is the impulse injected into the analog output when the input code in the DAC register changes state. It is normally specified as the area of the glitch in nV-s and is measured when the digital input code is changed by 1 LSB at the major carry transition (0x7FFF to 0x8000) (see Figure 33). Digital Feedthrough Digital feedthrough is a measure of the impulse injected into the analog output of the DAC from the digital inputs of the DAC, but is measured when the DAC output is not updated. It is specified in nV-s and measured with a full-scale code change on the data bus, that is, from all 0s to all 1s, and vice versa (see Figure 34). Rev.

Because it is a string of resistors, it is guaranteed monotonic. The AD5602/AD5612/AD5622 DACs are fabricated on a CMOS process. The architecture consists of a string DACs followed by an output buffer amplifier. Figure 37 shows a block diagram of the DAC architecture.

DAC Architecture Since the input coding to the DAC is straight binary, the ideal output voltage is given by R D VOUT = V DD x n 2 R 05446-023 where: D is the decimal equivalent of the binary code that is loaded to the DAC register; it can range from 0 to 255 (AD5602), 0 to 1023 (AD5612), or 0 to 4095 (AD5622). n is the bit resolution of the DAC. Figure 38. Resistor String Structure OUTPUT AMPLIFIER RESISTOR STRING The resistor string structure is shown in Figure 38. It is simply a string of resistors, each of value R. The code loaded to the DAC register determines at which node on the string the voltage is tapped off to be fed into the output amplifier. The voltage is The output buffer amplifier is capable of generating rail-to-rail voltages on its output, giving an output range of 0 V to VDD. It is capable of driving a load of 2 k in parallel with 1000 pF to GND. The source and sink capabilities of the output amplifier can be seen in Figure 27. The slew rate is 0.5 V/s with a halfscale settling time of 5 s with the output unloaded. Rev. C | Page 15 of 24 AD5602/AD5612/AD5622 Data Sheet SERIAL INTERFACE 3. When all data bits have been read or written, a stop condition is established. In write mode, the master pulls the SDA line high during the 10th clock pulse to establish a stop condition. In read mode, the master issues a no acknowledge for the ninth clock pulse (that is, the SDA line remains high). The master then brings the SDA line low before the 10th clock pulse, and then high during the 10th clock pulse to establish a stop condition. Table 7. Device Address Selection The AD5602/AD5612/AD5622 have 2-wire I2C-compatible serial interfaces (refer to I2C-Bus Specification, Version 2.1, January 2000, available from Philips Semiconductor). The AD5602/AD5612/AD5622 can be connected to an I2C bus as a slave device, under the control of a master device. See Figure 2 for a timing diagram of a typical write sequence. The AD5602/AD5612/AD5622 support standard (100 kHz), fast (400 kHz), and high speed (3.4 MHz) data transfer modes. Support is not provided for 10-bit addressing and general call addressing. ADDR GND VDD NC (No Connection) The AD5602/AD5612/AD5622 each have a 7-bit slave address. The five MSBs are 00011 and the two LSBs are determined by the state of the ADDR pin. The facility to make hardwired changes to ADDR allows the user to incorporate up to three of these devices on one bus as outlined in Table 7. A1 1 0 1 INPUT REGISTER The input register is 16 bits wide. Figure 39, Figure 40, and Figure 41 illustrate the contents of the input register for each part. Data is loaded into the device as a 16-bit word under the control of a serial clock input, SCL. The timing diagram for this operation is shown in Figure 2. The 16-bit word consists of four control bits followed by 8, 10, or 12 bits of data, depending on the device type. MSB (DB15) is loaded first. The first two bits are reserved bits that must be set to zero, the next two bits are control bits that select the mode of operation of the device (normal mode or any one of three power-down modes). See the Power-Down Modes section for a complete description. The remaining bits are left-justified DAC data bits, starting with the MSB and ending with the LSB. The 2-wire serial bus protocol operates as follows: 1. The master initiates data transfer by establishing a start condition, which is when a high-to-low transition on the SDA line occurs while SCL is high. The following byte is the address byte, which consists of the 7-bit slave address. The slave address corresponding to the transmitted address responds by pulling SDA low during the ninth clock pulse (this is termed the acknowledge bit). At this stage, all other devices on the bus remain idle while the selected device waits for data to be written to, or read from, its shift register. 2. Data is transmitted over the serial bus in sequences of nine clock pulses (eight data bits followed by an acknowledge bit). The transitions on the SDA line must occur during the low period of SCL and remain stable during the high period of SCL.

The DAC register is filled with zeros and the output voltage is 0 V where it remains until a valid write sequence is made to the DAC. This is useful in applications where it is important to know the state of the DAC output while it is in the process of powering up. POWER-DOWN MODES The AD5602/AD5612/AD5622 each contain four separate modes of operation. These modes are software-programmable by setting Bit PD1 and Bit PD0 in the control register. Table 8 shows how the state of the bits corresponds to the mode of operation of the device. When both bits are set to 0, the part works normally with its usual power consumption of 100 A maximum at 5 V. However, for the three power-down modes, the supply current falls to <150 nA (at 3 V). Not only does the supply current fall, but the output stage is internally switched from the output of the amplifier to a resistor network of known values. This gives the advantage of knowing the output impedance of the part while the part is in power-down mode. There are three different options. The output is connected internally to GND through a 1 k resistor, a 100 k resistor, or it is left open-circuited (three-state). Figure 42 shows the output stage.

Output Stage During Power-Down The bias generator, output amplifier, resistor string, and other associated linear circuitry are all shut down when the powerdown mode is activated. However, the contents of the DAC register are unaffected when in power-down. The time to exit power-down is typically 14 s for VDD = 5 V and 17 s for VDD = 3 V (see Figure 29). Rev. C | Page 17 of 24 AD5602/AD5612/AD5622 Data Sheet WRITE OPERATION Two bytes of data are then written to the DAC, the most significant byte followed by the least significant byte as shown in Figure 40; both of these data bytes are acknowledged by the AD5602/AD5612/AD5622. A stop condition follows. The write operations for the three DACs are shown in Figure 43, Figure 44, and Figure 45. When writing to the AD5602/AD5612/AD5622, the user must begin with a start command followed by an address byte (R/W = 0), after which the DAC acknowledges that it is prepared to receive data by pulling SDA low. 1 9 1 9 SCL SDA 0 0 0 1 1 A1 A0 R/W START BY MASTER 0 0 PD1 PD0 D7 D6 D5 D4 ACK.

The ADR293 voltage reference is recommended in this case. This requires 15 A of quiescent current and can therefore drive multiple DACs in the one system, if required. 10 x D VO = -5 V n 2 This is an output voltage range of 5 V with 0x000 corresponding to a -5 V output, and 0xFFF corresponding to a +5 V output.

For space-saving applications, the ADR425 is available in an SC70 package with excellent drift at 3ppm/C. It also provides very good noise performance at 3.4 V p-p in the 0.1 Hz to 10 Hz range.

The circuit in Figure 51 gives an output voltage range of 5 V. Rail-to-rail operation at the amplifier output is achievable using an AD820 or an OP295 as the output amplifier. The output voltage for any input code can be calculated as R2 D R1 + R2 VO = VDD x n x - VDD x R1 2 R1 where: D represents the input code in decimal. n represents the bit resolution of the DAC. When accuracy is important in a circuit, it is helpful to carefully consider the power supply and ground return layout on the board. The printed circuit board containing the AD5602/ AD5612/AD5622 should have separate analog and digital sections, each having its own area of the board. If the AD5602, AD5612, or AD5622 is in a system where other devices require an AGND to DGND connection, the connection should be made at one point only. This ground point should be as close as possible to the AD5602/AD5612/AD5622. The power supply to the AD5602/AD5612/AD5622 should be bypassed with 10 F and 0.1 F capacitors. The capacitors should be physically as close as possible to the device with the 0.1 F capacitor ideally right up against the device. The 10 F capacitors are the tantalum bead type. It is important that the 0.1 F capacitor has low effective series resistance (ESR) and effective series inductance (ESI), such as common ceramic types. This 0.1 F capacitor provides a low impedance path to ground for high frequencies caused by transient currents due to internal logic switching. The power supply line should have as large a trace as possible to provide a low impedance path and reduce glitch effects on the supply line. Clocks and other fast switching digital signals should be shielded from other parts of the board by digital ground. Avoid crossover of digital and analog signals if possible. When traces cross on opposite sides of the board, ensure that they run at right angles to each other to reduce feedthrough effects through the board. The best board layout technique is the microstrip technique where the component side of the board is dedicated to the ground plane only and the signal traces are placed on the solder side. However, the microstrip technique is not always possible with a 2-layer board. Rev.
