The ADCMP391 is a single, rail-to-rail input, low power comparator ideal for use in general-purpose applications. The device operates from a single supply voltage of 2.3 V to 5.5 V and draws a minimal amount of current. The ADCMP391 consumes only 18.6 µ of supply current. The low voltage and low current operation of the ADCMP391 makes it ideal for battery-powered systems.
The ADCMP391 features a common-mode input voltage range of 200 mV beyond rails, an offset voltage of 1 mV typical across the full common-mode range, and a UVLO monitor. In addition, the design of the comparator allows a defined output state upon power-up. The comparator generates a logic low output if the supply voltage is less than the UVLO threshold.
The ADCMP391 is available in an 8-lead, narrow body SOIC package. The ADCMP391 is specified to operate over the extended temperature range of -40°C to +125°C.
