ADCMP393 Quad Comparator with Known Power-Up State

The ADCMP391 / ADCMP392 / ADCMP393 are single/dual/quad rail-to-rail input, low power comparators ideal for use in general-purpose applications. These comparators operate from a single supply voltage of 2.3 V to 5.5 V and draw a minimal amount of current. The single ADCMP391 consumes only 18.6 µA of supply current. The dual ADCMP392 and the quad ADCMP393 consumes 22.1 µA and 26.8 µA of supply current, respectively. The low voltage and low current operation of these devices makes it ideal for battery-powered systems.

The comparators 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 comparators allows a defined output state upon power-up, a logic low output while the supply voltage is less than the UVLO threshold.

The ADCMP391 and ADCMP392 are available in 8-lead, narrow body SOIC package while the ADCMP393 is available in a 14-lead, narrow body SOIC package and a 14-lead TSSOP package. The comparators are specified to operate over the −40°C to +125°C extended temperature range.
