Overview
The ADA4932-1YCPZ-R2, produced by Analog Devices Inc., is a low-power differential ADC driver that represents the next generation of the AD8132 series. It offers 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 ADA4932-1 features an internal common-mode feedback loop that allows the output common-mode voltage to be user-adjustable, ensuring it matches the input of the ADC. This design also provides exceptional output balance and suppresses even-order harmonic distortion products.
