Overview
The CMP402GRUZ-REEL is a 65 ns low voltage comparator produced by Analog Devices Inc. This quad comparator features separate input and output supplies, allowing the input stage to operate from +3 V to as high as ±6 V, and the output to be supplied with either 3 V or 5 V. This flexibility makes it an excellent choice for interfacing with portable instrumentation and other applications requiring fast and reliable signal comparison.
