1 / 5 page 1/5 s LOW SUPPLY CURRENT: 0.53mA/AMPLI- FIER s CLASS AB OUTPUT STAGE: NO CROSS OVER DISTORTION s PIN COMPATIBLE WITH LM124 s LOW INPUT OFFSET VOLTAGE: 1mV s LOW INPUT OFFSET CURRENT: 2nA s LOW INPUT BIAS CURRENT: 30nA s GAIN BANDWIDTH PRODUCT: 1.3MHz s HIGH DEGREE OF ISOLATION BETWEEN AMPLIFIERS: 120dB s OVERLOAD PROTECTION FOR INPUTS AND OUTPUTS DESCRIPTION The LM148 consists of four independent, high gain internally compensated, low power opera- tional amplifiers which have been designed to pro- vide functional characteristics identical to those of the familiar UA741 operational amplifier. In addi- tion the total supply current for all four amplifiers is compatible 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 independently biasing each amplifier and using layout techniques qhich minimize thermal cou- pling. The LM148 can be used anywhere multiple UA741 type amplifiers are being used and in appli- cations where amplifier matching or high packaing density is required.
