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.
A fast, high precision differential input stage permits consistent propagation delay with a wide variety of signals in the common mode range from 2.0 V to +3.0 V. Outputs are complementary digital signals fully compatible with ECL 10 K and 10 KH logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50 to 2 V. A latch input is included which permits tracking,
track-hold, or sample-hold modes of operation.
The AD53519 is available in a 20-lead PLCC package.
