ADCMP567,pdf datasheet (Dual U

The ADCMP567 is an ultrafast voltage comparator fabr ica ted on AnalogDevices’ proprietary XFCB process. The device features 250 ps propaga tion delay with less than 35 ps overdrive dispe rsion. Overdrive dispersion, a particularly important char acteristic 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 PECL 10 K and 10 KH logicfamilies. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50 Ω to VDD − 2 V. A latch input is included, which permits tracking, track-and-hold, orsample-and-hold modes of operation.
The ADCMP567 is av ailable in a 32-lead LFCSP package.
