LM725

Operational Amplifier

General Description

The LM725/LM725A/LM725C are operational amplifiers fea-

turing superior performance in applications where low noise,

low drift, and accurate closed-loop gain are required. With

high common mode rejection and offset null capability, it is

especially suited for low level instrumentation applications

over a wide supply voltage range.

The LM725A has tightened electrical performance with

higher input accuracy and like the LM725, is guaranteed

over a −55˚C to +125˚C temperature range. The LM725C

has slightly relaxed specifications and has its performance

guaranteed over a 0˚C to 70˚C temperature range.
