The ADCMP391/ADCMP392/ADCMP393 are
INA+ OUTA INA–
single/dual/quad rail-to-rail input, low power comparators ideal
INB+
for use in general-purpose applications. These comparators
OUTB INB–
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
IND+ OUTD IND–
and the quad ADCMP393 consumes 22.1 µA and 26.8 µA of 103 supply current, respectively. The low voltage and low current

12206- operation of these devices makes it ideal for battery-powered Figure 3. systems. The comparators features a common-mode input voltage range of 200 mV beyond rails, an offset voltage of 1 mV typical across the ful 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.
