The AD96685 and AD96687 are ultrafast voltage comparators designed for high-speed applications such as triggers, line receivers, and threshold detection. The AD96685 is a single comparator with a 2.5 ns propagation delay, while the AD96687 is a dual comparator with identical performance. Both devices feature a 50 ps propagation delay dispersion and operate with ECL logic compatibility.
