GENERAL DESCRIPTION  
The ADCMP565 is an ultrafast voltage comparator fabricated  
on Analog Devices’ proprietary XFCB process. The device  
features 300 ps propagation delay with less than 50 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.  
APPLICATIONS  
High speed instrumentation  
Scope and logic analyzer front ends  
Window comparators  
High speed line receivers and signal restoration  
Threshold detection  
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.  
Peak detection  
High speed triggers  
Patient diagnostics  
Disk drive read channel detection  
Hand-held test instruments  
Zero-crossing detectors  
Clock drivers  
Automatic test equipment  
The ADCMP565 is available in a 20-lead PLCC package.
