Low-Cost Solution Available in Space-Saving
comparators are optimized for low-power consumption
SC70 Packages (Half the Size of SOT23)
while still providing a fast output response. They are designed for single-supply applications from 2.5V to ♦
Low 2.8µA Supply Current
5.5V, but can also operate from dual supplies. These ♦
3µs Propagation Delay
comparators have a 3µs propagation delay and con- sume 2.8µA of supply current per comparator over the ♦
Internal 4mV Comparator Hysteresis
-40°C to +125°C operating temperature range. The ♦
Comparator Output Swings Rail-to-Rail
combination of low-power, single-supply operation down to 2.5V, and ultra-small footprint makes these ♦
2.5 to 5.5V Single-Supply Voltage Range
devices ideal for portable applications. ♦
No Phase Reversal for Overdriven Inputs
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
5-Pin SC70 (MAX9021)
common-mode range extends from the negative supply
8-Pin SOT23 (MAX9022)
to within 1.1V of the positive supply. The design of the
8-Pin µMAX (MAX9022)
comparator-output stage substantially reduces switch-
14-Pin TSSOP (MAX9024)
ing current during output transitions, eliminating power- supply glitches.
Ordering Information
The MAX9021 single comparator is available in tiny 5- pin SC70 and SOT23 packages. The MAX9022 dual
PIN- PKG
comparator is available in 8-pin SOT23, µMAX®, and
PA RT TEMP RANGE PACKAGE CODE
SO packages, and the MAX9024 quad comparator is available in 14-pin TSSOP and SO packages.
