Overview
The AD8137YCPZ-R2, produced by Analog Devices Inc., is a low-cost differential driver with a rail-to-rail output. It is specifically designed for driving Analog-to-Digital Converters (ADCs) in systems that are sensitive to power and cost. The device features an internal common-mode feedback architecture, allowing for controlled output common-mode voltage and inherently balanced outputs. This architecture also suppresses even-order harmonic distortion products, making it highly suitable for various applications requiring precise signal handling.
