Overview
The AD96685BRZ-REEL, produced by Analog Devices Inc., is an ultrafast voltage comparator. This single comparator device is characterized by its exceptionally fast propagation delay of 2.5 ns, making it suitable for high-speed applications. It features a high precision differential input stage that ensures consistent propagation delay across a wide range of signals within the common-mode range from -2.5 V to +5 V. The device is compatible with ECL 10 K and 10 KH logic families and includes a level sensitive latch input, enabling tracking, track-hold, or sample-hold modes of operation.
