General Description

The MAX9030/MAX9031/MAX9032/MAX9034 single/

dual/quad comparators are optimized for single-supply

applications from +2.5V to +5.5V but can also be oper-

ated from dual supplies. These comparators have a

188ns propagation delay and consume 35µA of supply

current per comparator over the -40°C to +125°C oper-

ating temperature range. The combination of low-

power, single-supply operation down to +2.5V, and

ultra-small footprint makes these devices ideal for

portable applications.

The MAX9030 is a low-cost single comparator with

shutdown. The MAX9031, MAX9032, and MAX9034 are

low-cost single, dual, and quad comparators without

shutdown, respectively. The comparators’ 4mV of built-

in hysteresis provides noise immunity and prevents

oscillations even with a slow-moving input signal. The

input common-mode range extends from the negative

supply to within 1.1V of the positive supply. The design

of the comparator output stage substantially reduces

switching current during output transitions, virtually

eliminating power-supply glitches.

The MAX9030 single comparator with shutdown is avail-

able in the space-saving 6-pin SC70 and SOT23 pack-

ages. The MAX9031 single comparator is available in tiny

5-pin SC70 and SOT23 packages. The MAX9032 dual

comparator is available in 8-pin SOT23 and µMAX pack-

ages, and the MAX9034 quad comparator is available in

a 14-pin TSSOP package.
