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.
