DESCRIPTION

SO14

(Plastic Micropackage)

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.
