LM248

DifferentialĂInput OperationalĂAmplifiers The LM348 series is a true quad MC1741. Integrated on a single monolithic chip are four independent, low power operational amplifiers which have been designed to provide operating characteristics identical to those of the industry standard MC1741, and can be applied with no change in circuit performance. In addition, the total supply current for all four amplifiers is comparable to the supply current of a single MC1741. Other features include input offset currents and input bias currents which are much less than the MC1741 industry standard. The LM348 can be used in applications where amplifier matching or high packing density is important. Other applications include high impedance buffer amplifiers and active filter amplifiers. Each Amplifier is Functionally Equivalent to the MC1741 Low Input Offset and Input Bias Currents Class AB Output Stage Eliminates Crossover Distortion Pin Compatible with MC3403 and LM324 True Differential Inputs Internally Frequency Compensated Short Circuit Protection Low Power Supply Current (0.6 mA/Amplifier) Order this document by LM348/D LM348 LM248 DIFFERENTIAL INPUT OPERATIONAL AMPLIFIERS SEMICONDUCTOR TECHNICAL DATA 14 1 N SUFFIX PLASTIC PACKAGE CASE 646 14 1 D SUFFIX PLASTIC PACKAGE CASE 751A (SO–14) Representative Schematic Diagram (1/4 of Circuit Shown) Noninverting Input Inverting Input 4.5 k 39 k 30 pF 7.5 k 10 k 50 k 1.0 k 5.0 k 50 k 50 MOTOROLA ANALOG IC DEVICE DATA PIN ...
