Overview
The ADCMP395ARMZ, produced by Analog Devices Inc., is a dual, rail-to-rail input, low power comparator designed for general-purpose applications. This device operates from a single supply voltage ranging from 2.3 V to 5.5 V and is particularly suited for battery-powered systems due to its low power consumption of 37.2 µA. The ADCMP395 features a high accuracy reference output voltage of 1 V ± 0.9% and a rail-to-rail common-mode input voltage range, extending 200 mV beyond the supply rails. It also includes an undervoltage lockout (UVLO) monitor that ensures the comparator output is logic low when the supply voltage is below the UVLO threshold. The device is available in a 10-lead MSOP package and is specified to operate over an extended temperature range of −40°C to +125°C.
