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.
