1 / 9 page . LOW SUPPLY CURRENT : 0.53mA/AMPLIFIER . CLASS AB OUTPUT STAGE : NO CROSS- OVER DISTORTION . PIN COMPATIBLE WITH LM124 . LOW INPUT OFFSET VOLTAGE : 1mV . LOW INPUT OFFSET CURRENT : 2nA . LOW INPUT BIAS CURRENT : 30nA . GAIN BANDWIDTH PRODUCT : 1.3MHz . HIGH DEGREE OF ISOLATION BETWEEN AMPLIFIERS : 120dB . OVERLOAD PROTECTION FOR INPUTS AND OUTPUTS DESCRIPTION The LM148 consists of four independent,high gain internally compensated, low power operational amplifiers which have been designed to provide functionalcharacteristics identical to those of the fa- miliar UA741 operational amplifier. In addition the total supply current for all four amplifiers is compa- rable to the supply current of a single UA741 type op amp. Other features include input offset current and input bias current which are much less than those of a standard UA741. Also, excellent isolation between amplifiers has been achieved by inde- pendently biasing each amplifier and using layout techniques which minimize thermal coupling. The LM148 can be used anywhere multiple UA741 type amplifiers are being used and in applications where amplifier matching or high packing density is required.
