GENERAL DESCRIPTION
The OP193 family of single-supply operational amplifiers fea-
tures 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 family can operate down to 1.7 volts or ±0.85 volts.
The combination of high accuracy and low power operation
make the OP193 family useful for battery-powered equipment.
Its 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 family is specified for single +2 volt through dual
±15 volt operation over the HOT (–40°C to +125°C) temperature
range. They are available in plastic DIPs, plus SOIC surface-
mount packages.
