Overview
The AD8652ARMZ 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 features the newest generation of DigiTrim® in-package trimming. This technology measures and corrects the offset over the entire input common-mode range, reducing distortion from VOS variation compared to other rail-to-rail amplifiers. The AD8652ARMZ is designed for use in a wide range of applications, including optical communications, laser source drivers/controllers, broadband communications, high-speed ADCs and DACs, microwave link interfaces, cell phone PA control, video line drivers, and audio systems.
