The MAX9021/MAX9022/MAX9024 single/dual/quad

comparators are optimized for low-power consumption

while still providing a fast output response. They are

designed for single-supply applications from 2.5V to

5.5V, but can also operate from dual supplies. These

comparators have a 3µs propagation delay and con-

sume 2.8µA of supply current per comparator over the

-40°C to +125°C operating 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 MAX9021/MAX9022/MAX9024 have 4mV of built-in

hysteresis to provide noise immunity and prevent oscil-

lations 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 switch-

ing current during output transitions, eliminating power-

supply glitches.

The MAX9021 single comparator is available in tiny 5-

pin SC70 and SOT23 packages. The MAX9022 dual

comparator is available in 8-pin SOT23, µMAX

SO packages, and the MAX9024 quad comparator is

available in 14-pin TSSOP and SO packages.
