LM4250

Programmable Operational Amplifier

General Description

The LM4250 and LM4250C are extremely versatile program-

mable monolithic operational amplifiers. A single external

master bias current setting resistor programs the input bias

current, input offset current, quiescent power consumption,

slew rate, input noise, and the gain-bandwidth product. The

device is a truly general purpose operational amplifier.

The LM4250C is identical to the LM4250 except that the

LM4250C has its performance guaranteed over a 0˚C to

+70˚C temperature range instead of the −55˚C to +125˚C

temperature range of the LM4250.
