The ADCMP561/ADCMP562 are high speed comparators fabricated on Analog Devices' proprietar y XFCB process. The devices feature a 700 ps propagation delay with less than 75 ps overdrive dispersion. Dispersion, a measure of the difference in propagation delay under differing overdrive conditions, is a particularly important characteristic of comparators. A separate programmable hysteresis pin is available on the ADCMP562.
