Overview
The AD8652ARMZ-REEL, produced by Analog Devices Inc., is a high-precision, low-noise, low-distortion rail-to-rail CMOS operational amplifier. This dual amplifier operates from a single-supply voltage ranging from 2.7 V to 5.5 V, making it versatile for various applications. The AD8652 features the latest generation of DigiTrim® in-package trimming, which ensures precise offset voltage correction over the entire input common-mode range, thereby reducing distortion. This amplifier is known for its high gain bandwidth of 50 MHz, low noise performance of 4.5 nV/√Hz, and a typical voltage offset of 100 μV from a 5 V supply.
