GENERAL DESCRIPTION

The OP193/OP293 are single-supply operational amplifiers that

feature a combination of high precision, low supply current, and

the ability to operate at low voltages. For high performance in

single-supply systems, the input and output ranges include

ground, and the outputs swing from the negative rail to within

600 mV of the positive supply. For low voltage operation, the

OP193/OP293 can operate down to +1.7 V or ±0.85 V.

The combination of high accuracy and low power operation

make the OP193/OP293 useful for battery-powered equipment.

The part’s low current drain and low voltage operation allow it

to continue performing long after other amplifiers have ceased

functioning either because of battery drain or headroom.

The OP193/OP293 are specified for single +2 V through dual

±15 V operation over the extended (−40°C to +125°C) temperature

range. They are available in SOIC surface-mount packages.
