The AD822ARZ is a rail to rail, FET input dual op amp (Operational Amplifier) in 8 pin NSOIC package. This dual precision, low power op amp can operate from single supply of 5V to 30V or dual supplies of ±2.5V to ±15V. It has true single supply capability with an input voltage range extending below negative rail allowing the AD822 to accommodate input signals below ground in single supply mode. Output voltage swing extends to within 10mV of each rail providing the maximum output dynamic range.
