Overview
The AD8651ARMZ is a high-precision, low-noise, low-distortion, rail-to-rail CMOS operational amplifier produced by Analog Devices Inc. It operates from a single-supply voltage of 2.7V to 5.5V and features the newest generation of DigiTrim® in-package trimming. This technology ensures precise offset voltage and common-mode rejection ratio (CMRR) over the entire input common-mode range and across the extended industrial temperature range of -40°C to 125°C. The amplifier is designed for applications requiring high accuracy and low noise, making it suitable for various high-performance applications.
