Overview
The CMP04FSZ-REEL, produced by Analog Devices Inc., is a quad low power, precision comparator integrated circuit. This device features four independent comparators, each offering high performance characteristics such as very low offset voltage, low output saturation voltage, and high gain. The CMP04 is designed for single or dual-supply operation, with an input voltage range that includes ground for single-supply operation and V– for split supplies. It is particularly suited for precision applications requiring minimal power consumption, with a low power supply current of 2 mA that is independent of the supply voltage.
