AD820BN Datasheet PDF - Analog Devices

PRODUCT DESCRIPTION
The AD820 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. It has true single supply capability with an input voltage range extending below the negative rail, allowing the AD820 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.
