Description

The LM248 and LM348 consist of four

independent, high-gain internally-compensated,

low-power operational amplifiers which have been

designed to provide functional characteristics

identical to those of the familiar UA741

operational amplifier. In addition, the total supply

current for all four amplifiers is compatible with

the supply current of a single UA741 type

operational amplifier. 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 which minimize

thermal coupling.

The LM248 and LM348 can be used where

multiple UA741 type amplifiers are being used

and in applications where amplifier matching or

high packaging density is required.
