Overview
The AD822TRZ-EP is a dual precision, low power FET-input operational amplifier (op amp) produced by Analog Devices Inc. This device is designed for high precision and low power consumption, making it suitable for a variety of applications. The AD822TRZ-EP operates from a single supply of 5 V to 30 V or dual supplies of ±2.5 V to ±15 V, offering true single-supply capability with an input voltage range extending below the negative rail. This allows the AD822 to accommodate input signals below ground in single-supply mode. The output voltage swing extends to within 10 mV of each rail, providing maximum output dynamic range.
