ADCMP565

The ADCMP565 is an ultrafast voltage comparator fabricated on ADI’s proprietary XFCB process. The device features 300 ps propagation delay with less than 50 ps overdrive dispersion. Overdrive dispersion,a particularly important characteristic of high speed comparators 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 -2.0 V to +3.0 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 latch input is included which permits tracking, track-hold, or sample-hold modes of operation.

The ADCMP565 is available in a 20-lead PLCC package.
