Overview
The AD8137YR-REEL7, produced 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 is manufactured using Analog Devices' proprietary second-generation XFCB process, enabling high performance with very low power consumption. The AD8137 is easy to apply and offers internal common-mode feedback architecture, allowing the output common-mode voltage to be controlled by a single pin. It supports both fully differential and single-ended-to-differential gain configurations and is available in small 8-lead SOIC and 3 mm × 3 mm LFCSP packages.
