Overview
The AD8137YR-REEL, manufactured by Analog Devices Inc., is a low-cost, low-power differential ADC driver. This component is designed to drive analog-to-digital converters (ADCs) in systems that are sensitive to power and cost. It features a rail-to-rail output and an internal common-mode feedback architecture, allowing for the control of the output common-mode voltage through a single pin. The AD8137 is easy to apply and supports both fully differential and single-ended-to-differential gain configurations. It is particularly beneficial in critical low power applications due to its power-down feature.
