GENERAL DESCRIPTION
The ADCMP566 is an ultrafast voltage comparator fabricated
on Analog Devices’ proprietary XFCB process. The device
features 250 ps propagation delay with less than 35 ps overdrive
dispersion. Overdrive dispersion, a particularly important
characteristic of high speed comparators, is a measure of the
difference in propagation delay under differing overdrive
conditions.
A fast, high precision differential input stage permits consis-
tent 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 Ω
to −2 V. A latch input is included, which permits tracking,
track-and-hold, or sample-and-hold modes of operation.
The ADCMP566 is available in a 32-lead LFCSP package.
