The 50mV internal hysteresis prevents output chatter on slow-moving input signals near the trip point. ## Supply flexibility and signal integrity for threshold sensing The supply range spans 2.5V to 11V in single-supply mode, or ±1.25V to ±5.5V with dual supplies — the same part covers 3V, 5V, and 10V rails without a regulator change. Input offset voltage is specified at 10mV maximum at 5V, which sets the practical threshold accuracy floor for the window detector or overvoltage latch. Common-mode and power-supply rejection both typify at 80dB, meaning the trip point shifts less than 100µV per volt of supply ripple or common-mode variation. In a noisy industrial backplane, this keeps the comparator from false-triggering on supply transients. ## 8-SOIC footprint and commercial temperature grade The supplier device package is listed as 8-SOIC, matching the JEDEC MO-012 outline. Operating temperature is limited to 0°C to 70°C, which restricts this variant to commercial or controlled indoor environments. For extended-temperature or automotive deployment, a different grade of the same comparator family would be required. RoHS3 compliant per the current lifecycle record, the MAX981CSA+ meets EU Directive 2015/863 without exemption claims.","metaTitle":"MAX981CSA+ Analog Devices Comparator with Voltage Reference","metaDescription":"MAX981CSA+ single comparator with integrated voltage reference. 4µA quiescent current, 50mV hysteresis, 2.5V-11V supply.
