Overview
The AD8137YRZ-REEL, manufactured by Analog Devices Inc., is a low-cost, low-power differential amplifier designed to drive analog-to-digital converters (ADCs) in systems sensitive to power and cost. This component is built on Analog Devices' proprietary second-generation XFCB process, enabling high performance with minimal power consumption. It features a rail-to-rail output and an internal common-mode feedback architecture, which allows for the control of the output common-mode voltage and inherently balanced outputs. The AD8137 is available in 8-lead SOIC and 3 mm × 3 mm LFCSP packages and operates over an extended industrial temperature range of −40°C to +125°C.
