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 dif-

fering 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 sen-

sitive latch input is included which permits tracking, track-hold,

or sample-hold modes of operation.

The AD96685 and AD96687 are available in both industrial,

–25°C to +85°C, and military temperature ranges. Industrial

range devices are available in 16-pin DIP, SOIC, and 20-lead

PLCC; additionally, the AD96685 is available in a 10-pin,

TO-100 metal can.
