Overview
The AD8561ARUZ-REEL, produced by Analog Devices Inc., is a high-performance, ultrafast single-supply comparator. This component is designed for applications requiring fast response times and low power consumption. The AD8561 features separate input and output stages, allowing for flexible supply configurations, including single supply operation from 3 V to 10 V and dual supply operation from ±5 V. This comparator is particularly suited for high-speed timing circuits, clock recovery, and digital communications due to its fast 7 ns propagation delay and closely matched rising and falling propagation delays.
