Product Details
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 Ohm to -2 V. A level sensitive 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.
