GENERAL DESCRIPTION

The AD53519 is an ultrafast voltage comparator fabricated on ADI’s proprietary XFCB process. The device features 300 ps propagation delay with better than 75 ps overdrive dispersion. Dispersion is a particularly important characteristic of high speed comparators. It is a measure of the difference in propagation delay under differing overdrive conditions.
