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
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.
