Overview
The CMP401GRUZ-REEL, produced by Analog Devices Inc., is a quad comparator with a propagation delay of 23 ns. This component is part of the CMP401 and CMP402 series, which are designed for low-voltage applications and offer separate input and output supplies. This feature allows 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, making it versatile for various interface logic and supply configurations. The CMP401 is specified over the extended industrial temperature range of –40°C to +125°C and is available in a 16-lead TSSOP package.
