LM725 Datasheet | National Semiconductor

Description The LM725/LM725A/LM725C are operational amplifiers featuring superior performance in applications where low noise, low drift, and accurate closed-loop gain are required. With high mon 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.
