Overview
The ADCMP396ARZ-RL7, produced by Analog Devices Inc., is a quad, rail-to-rail input, low power comparator designed for general-purpose applications. This device is particularly suited for battery-powered systems due to its low voltage and low current operation. It operates from a single supply voltage of 2.3 V to 5.5 V and consumes a minimal supply current of 41.61 µA, making it highly efficient for power-sensitive designs. The comparator features a high accuracy reference output voltage of 1 V ± 0.9% and has an open-drain output stage that requires an external pull-up resistor to achieve the desired logic high voltage level.
