GENERAL DESCRIPTION

The ADCMP565 is an ultrafast voltage comparator fabricated on Analog Devices’ 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.
