Low-Cost, Ultra-Small, Single/Dual/Quad
Single-Supply Comparators
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

All devices are production tested at +25°C. All temperature limits are guaranteed by design.
Comparator Input Offset is defined as the center of the hysteresis zone.
Hysteresis is defined as the difference of the trip points required to change comparator output states.
V
OD
is the overdrive that is beyond the offset and hysteresis-determined trip points.
Rise and fall times are measured between 10% and 90% at OUT.
