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.
Features
n ±1V to ±18V power supply operation
n 3 nA input offset current
n Standby power consumption as low as 500 nW
n No frequency compensation required
n Programmable electrical characteristics
n Offset voltage nulling capability
n Can be powered by two flashlight batteries
n Short circuit protection
