Overview
The CMP401GS-REEL, produced by Analog Devices Inc., is a 23 ns low voltage comparator. This quad comparator features separate input and output supplies, allowing the input stage to operate from +3 V to as high as ±6 V, while the output can 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 comparison functions.
