FEATURES
Operates from +1.7 V to ±18 V Low supply current: 15 µA/amplifier Low offset voltage: 100 µV maximum Outputs sink and source: ±8 mA No phase reversal Single- or dual-supply operation High open-loop gain: 600 V/mV Unity-gain stable APPLICATIONS
Digital scales Strain gages Portable medical equipment Battery-powered instrumentation Temperature transducer amplifier GENERAL DESCRIPTION
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.
