Overview
The ADA4932-2YCPZ-R2, produced by Analog Devices Inc., is a low-power differential ADC driver that represents the next generation of the AD8132 series. It is designed to offer higher performance, lower noise, and reduced power consumption. This amplifier is ideal for driving high-performance analog-to-digital converters (ADCs) in both single-ended-to-differential and differential-to-differential configurations. The ADA4932-2 features an internal common-mode feedback loop, which allows for user-adjustable output common-mode voltage to match the input of the ADC, ensuring exceptional output balance and suppression of even-order harmonic distortion products.
