The single OP193, dual OP293, and quad OP493 precision op amps from Analog Devices operate from supplies as low as 1.7V and provide minimum/maximum specifications for 2V operation. Applications include portable instrumentation, medical equipment, portable scales, battery-management systems, and others requiring minimum current and maximum accuracy.

Offset voltage is 75 µV with 1.25 µV/°C of drift and 15-nA input-bias current. When the devices operate with a 2V supply, current drain per amplifier is 13.2 µA. Open-loop gain is 600V/mV, and gain-bandwidth product is 25 kHz. The op amps include input-overvoltage protection, can source and sink 8 mA, and operate at 1.7V (±0.85V) to ±18V. The single, dual, and quad units, available in plastic DIP and SOIC packages, cost $1.37, $2.07, and $2.73, respectively (1000).
