The MAX931-MAX934 single, dual, and quad micropower,

low-voltage comparators plus an on-board 2% accurate

reference feature the lowest power consumption available.

These comparators draw less than 4µA supply current

ove r te mp e ra ture (MAX931), a nd inc lud e a n inte rna l

1.182V ±2% voltage reference, programmable hysteresis,

and TTL/CMOS outputs that sink and source current.

♦ Ultra-Low 4µA Max Quiescent Current

Over Extended Temp. Range (MAX931)

♦ Power Supplies:

Single +2.5V to +11V

Dual ±1.25V to ±5.5V

♦ Input Voltage Range Includes Negative Supply

♦ Internal 1.182V ±2% Bandgap Reference

♦ Adjustable Hysteresis

Id e a l for 3V or 5V s ing le -s up p ly a p p lic a tions , the

MAX931-MAX934 operate from a single +2.5V to +11V

s up p ly (or a ± 1.25V to ± 5V d ua l s up p ly), a nd e a c h

c omp a ra tor’s inp ut volta g e ra ng e e xte nd s from the

negative supply rail to within 1.3V of the positive supply.

♦ TTL-/CMOS-Compatible Outputs

♦ 12µs Propagation Delay (10mV Overdrive)

♦ No Switching Crowbar Current

The MAX931-MAX934’s unique output stage continuously

sources as much as 40mA. And by eliminating power-

supply glitches that commonly occur when comparators

c ha ng e log ic s ta te s , the MAX931-MAX934 minimize

parasitic feedback, which makes them easier to use.

♦ 40mA Continuous Source Current

♦ Available in Space-Saving µMAX Package

The single MAX931 and dual MAX932/MAX933 provide a

unique and simple method for adding hysteresis without

feedback and complicated equations, using the HYST pin

and two resistors.
