Product Summary

The AD820AR is a precision, low power FET input op amp that can operate from a single supply of 5 V to 36 V, or dual supplies of ±2.5 V to ±18 V. It has true single-supply capability. It is suitable for battery-powered precision instrumentation, photodiode preamps active filters, 12-bit to 14-bit data acquisition systems, medical instrumentation, low power references and regulators.
