GENERAL DESCRIPTION
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.
