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 parts 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 (40C to +125C) temperature range. They are available in SOIC surface-mount packages. Rev.
