National Semiconductor Semiconductors Linear |.C.s - Operational Amplifiers LM1558 and LM1458 Dual Operational Amplifiers REFERENCE TABLE Code Stock No. LM1538H _ 33138G LM1458H 31057H LM1458N 31149X GENERAL DESCRIPTION The LM1558/LM1458 is a general purpose dual operational amolitier. The two amolifiers share a common bias network and power supply leads. Otherwise their operation is completely independent. Features of the LM1558/LM1458 include offset nulling, short circuit protection, internal frequency compensation, wide common mode and differential mode range. Power drain is reduced by sharing bias resistors. FEATURES No frequency compensation required Short-circuit protection Wide common-mode and differential voltage ranges Low-power consumption No fatch-up TO-99 and 8-lead mini DIP ABSOLUTE MAXIMUM RATINGS CONNECTION DIAGRAM LM1458H LM1558H vt OutputA Output B Top View Inverting inverting Input A Input B Non-inverting Input B Non-Inverting Input A See outline drawing No. 97 for dimensions.
