Overview
The AD8651ARZ is a high-precision, low-noise, low-distortion, rail-to-rail CMOS operational amplifier produced by Analog Devices Inc. This amplifier operates from a single-supply voltage of 2.7V to 5.5V and is designed for a wide range of applications requiring high accuracy and low noise. The AD8651ARZ features the newest generation of DigiTrim® in-package trimming, which measures and corrects the offset over the entire input common-mode range, reducing distortion from VOS variation. This makes it particularly suitable for applications where precision and stability are critical.
