Overview
The ADCMP565BPZ is a dual ultrafast voltage comparator produced by Analog Devices Inc. It is fabricated on Analog Devices' proprietary XFCB process, which enables high-speed and high-precision operations. This comparator is designed for applications requiring fast and accurate voltage comparisons, with a propagation delay of 300 ps and a propagation delay dispersion of less than 50 ps. The device features differential ECL compatible outputs and includes a latch input for various modes of operation such as tracking, track-hold, or sample-hold. It is available in a 20-lead PLCC package.
