19-1842; Rev 2; 1/07 Micropower, Ultra-Small, Single/Dual/Quad,
Single-Supply Comparators
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 consume 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 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, eliminating powersupply glitches.
The MAX9021 single comparator is available in tiny 5pin SC70 and SOT23 packages. The MAX9022 dual
comparator is available in 8-pin SOT23, µMAX®, and
SO packages, and the MAX9024 quad comparator is
available in 14-pin TSSOP and SO packages. Features
