Overview
The ADCMP566BCPZ is an 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. The device features a propagation delay of 250 ps with less than 35 ps overdrive dispersion, making it highly suitable for applications requiring fast and accurate signal comparison. The comparator has a differential input stage that supports a wide common-mode range from -2.0 V to +3.0 V and an input differential range of ±5 V. The outputs are ECL compatible, providing sufficient drive current to directly drive transmission lines terminated in 50 Ω to -2 V.
