National Semiconductor LM725 Operational

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.
