ADCMP562 (ADCMP561 / ADCMP562) Dual High Speed PECL Comparators

The ADCMP561/ADCMP562 are high speed comparators fabricated on Analog Devices’ proprietary 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 separ.
