GENERAL DESCRIPTION

ADCMP393

INA+

OUTA

INA–

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.

Figure 3.

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.
