ADCMP567BCPZ

Product Summary

The ADCMP567BCPZ is an ultrafast voltage comparator fabricated on Analog Devices proprietary XFCB process. The ADCMP567BCPZ features 250 ps propagation delay with less than 35 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. The ADCMP567BCPZ Outputs are complementary digital signals fully compatible with PECL 10 K and 10 KH logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50 Ω to VDD －2 V. A latch input is included, which permits tracking, track-and-hold, or sample-and-hold modes of operation.
