Overview
The AD820ARZ-REEL, manufactured by Analog Devices Inc., is a precision, low power FET input operational amplifier. This device is designed for single-supply or dual-supply operation, making it highly versatile for various applications. It can operate from a single supply of 5 V to 36 V or dual supplies of ±2.5 V to ±18 V. The AD820ARZ-REEL features true single-supply capability with an input voltage range extending below the negative rail, allowing it 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.
