ADCMP392:  Dual Comparator with Known Power-Up State

Product Details

Product Status:Recommended for New Designs

The ADCMP392 is a dual, 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 quad ADCMP392 consumes only 22.1 μA of supply current. The low voltage and low current operation of the ADCMP392 makes it ideal for battery-powered systems.

The ADCMP392 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 ADCMP392 is available in a 8-lead, narrow body SOIC package. The ADCMP392 is specified to operate over the extended temperature range of −40°C to +125°C.
