Overview
The ADA4932-1YCPZ-RL, produced by Analog Devices Inc., is a high-performance differential amplifier designed to drive high-performance analog-to-digital converters (ADCs). It is part of the next generation of AD8132 amplifiers, offering improved performance, lower noise, and reduced power consumption. Fabricated using Analog Devices' proprietary silicon-germanium (SiGe) complementary bipolar process, this amplifier is ideal for single-ended-to-differential or differential-to-differential configurations. The ADA4932-1YCPZ-RL features an internal common-mode feedback loop, allowing for adjustable output common-mode voltage and exceptional output balance, as well as suppression of even-order harmonic distortion products.
