The AD822-EP is a dual precision, low power FET input op
800 μA maximum quiescent current per amplifier
amp that can operate from a single supply of 5 V to 30 V or dual
Unity-gain bandwidth: 1.8 MHz
supplies of ±2.5 V to ±15 V. It has true single-supply capability
Slew rate of 3 V/μs
with an input voltage range extending below the negative rail,
Good dc performance
allowing the AD822 to accommodate input signals below
800 μV maximum input offset voltage
ground in the single-supply mode. Output voltage swing
