The CMP402GRUZ-REEL is a quad Low Voltage Comparator with separate input and output supplies. Separate supplies enable the input stage to be operated from 3V to as high as ±6V. The output can be supplied with either 3 or 5V as determined by the interface logic or available supplies. Independent input and output supplies combined with fast propagation make the CMP402 excellent choice for interfacing to portable instrumentation.
