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.
