General Description
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, and SO
packages, and the MAX9024 quad comparator is avail-
able in 14-pin TSSOP and SO packages.
