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.
