GENERAL DESCRIPTION

The AD96685 and AD96687 are ultrafast voltage comparators.

The AD96685 is a single comparator with 2.5 ns propagation

delay; the AD96687 is an equally fast dual comparator. Both

devices feature 50 ps propagation delay dispersion which is a

particularly important characteristic of high-speed comparators.

It is a measure of the difference in propagation delay under

differing overdrive conditions.

A fast, high precision differential input stage permits consistent

propagation delay with a wide variety of signals in the common-

mode range from –2.5 V to +5 V. Outputs are complementary

digital signals fully compatible with ECL 10 K and 10 KH logic

families. The outputs provide sufficient drive current to directly

drive transmission lines terminated in 50 Ω to –2 V. A level

sensitive latch input which permits tracking, track-hold, or

sample-hold modes of operation is included.

The AD96685 is available in industrial –25°C to +85°C range

in 16-pin SOIC.

The AD96687 is available in industrial range –25°C to +85°C,

in 16-pin DIP, SOIC, and 20-lead PLCC.
