ADCMP553BRMZ

ADCMP553 is a single-supply, high speed comparator fabricated on Analog Devices, Inc., proprietary XFCB process. This device feature a 500ps propagation delay with less than 125ps overdrive dispersion. Overdrive dispersion, a measure of the difference in propagation delay under differing overdrive conditions, It is particularly important characteristic of high speed comparators. A latch input is included and permits tracking, track-and-hold, or sample-and-hold modes of operation. The latch input pins contain internal pullups that set the latch in tracking mode when left open. It is widely used in application such as automatic test equipment, high speed instrumentation, scope and logic analyser front ends, window comparators, high speed line receivers, threshold detection, peak detection, high speed triggers, patient diagnostics, disk drive read channel detection, hand-held test instruments, zero crossing detectors, line receivers and signal restoration, clock drivers etc.
