DESCRIPTION

The

µPC4250 is a highly versatile monolithic operational amplifier. The quiescent power dissipation, input offset and

bias current, slew rate and gain-bandwidth products are determined by a single external programming resistor. Since the

µPC4250 is in effect different op amps for each externally programmed set current, it is possible to use a single stock

item for a variety of circuit function in a system.

FEATURES

• Wide supply voltage range: ±1 V to ±18 V

• Programmable electrical characteristics

Power consumption, slew rate, etc.

• Internal frequency compensation

• Offset voltage null capability

• Output short circuit protection
