Product Introduction

Overview

The AD820BRZ-REEL7, produced by Analog Devices Inc., is a precision, low-power FET input operational amplifier. It is designed for single-supply operation from 5 V to 36 V or dual-supply operation from ±2.5 V to ±18 V. This op amp is notable for its true single-supply capability, allowing the input voltage range to extend below the negative rail, and its rail-to-rail output voltage swing. The AD820 is optimized for low power consumption, high precision, and excellent load drive capabilities, making it versatile for various applications.
