Micropower, Ultra-Small, Single/Dual/Quad,  
Single-Supply Comparators  
General Description  
Features  
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.  
ꢀ Low-Cost Solution Available in Space-Saving  
SC70 Packages (Half the Size of SOT23)  
ꢀ Low 2.8µA Supply Current  
ꢀ 3µs Propagation Delay  
ꢀ Internal 4mV Comparator Hysteresis  
ꢀ Comparator Output Swings Rail-to-Rail®  
ꢀ 2.5 to 5.5V Single-Supply Voltage Range  
ꢀ 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  
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.  
ꢀ Space-Saving Packages  
5-Pin SC70 (MAX9021)  
8-Pin SOT23 (MAX9022)  
8-Pin µMAX (MAX9022)  
14-Pin TSSOP (MAX9024)  
Ordering Information  
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.
