Product Summary

The AD820AN is a precision, low power FET input op amp that can operate from a single supply of +3.0 V to 36 V, or dual supplies of ±1.5 V to ±18 V. The AD820AN has true single supply capability with an input voltage range extending below the negative rail, allowing the AD820AN to accommodate input signals below ground in the single supply mode. Output voltage swing extends to within 10 mV of each rail providing the maximum output dynamic range. The AD820AN is suitable for Battery Powered Precision Instrumentation, Photodiode Preamps, Active Filters, 12- to 14-Bit Data Acquisition Systems, Medical Instrumentation and Low Power References and Regulators.
