Analog Comparators Ultra Fast ECL Single Comparator

The AD96685 and AD96687 are ultrafast voltage comparators. The AD96685 is a single comparator with a propagation delay of 2.5 ns, while the AD96687 is an equally fast dual comparator. Both devices exhibit a propagation delay dispersion of 50 ps, a crucial characteristic for high-speed comparators, indicating the difference in propagation delay under varying overdrive conditions.

Featuring a fast, high-precision differential input stage, these comparators maintain consistent propagation delay across a broad range of signals within the common-mode range from -2.5 V to +5 V. The outputs consist of complementary digital signals fully compatible with ECL 10 K and 10 KH logic families. These outputs provide ample drive current to directly interface with transmission lines terminated in 50 Ohms to -2 V. The inclusion of a level-sensitive latch input allows for tracking, track-hold, or sample-hold modes of operation.

Both the AD96685 and AD96687 are available in industrial temperature ranges (-25°C to +85°C) and military temperature ranges. Industrial range devices are offered in 16-pin DIP, SOIC, and 20-lead PLCC packages. Additionally, the AD96685 is available in a 10-pin TO-100 metal can.
