Low-Cost, Ultra-Small, Single/Dual/Quad  
Single-Supply Comparators  
General Description  
Features  
The MAX9030/MAX9031/MAX9032/MAX9034 single/  
dual/quad comparators are optimized for single-supply  
applications from +2.5V to +5.5V but can also be oper-  
ated from dual supplies. These comparators have a  
188ns propagation delay and consume 35µA of supply  
current per comparator over the -40°C to +125°C oper-  
ating 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.  
o Low-Cost Solution Available in Space-Saving  
SC70 Packages (MAX9030/MAX9031)  
o +2.5 to +5.5V Single-Supply Voltage Range  
o Comparator Output Swings Rail-to-Rail®  
o Internal 4mV Comparator Hysteresis  
o 188ns Propagation Delay  
o Low 35µA Supply Current  
The MAX9030 is a low-cost single comparator with  
shutdown. The MAX9031, MAX9032, and MAX9034 are  
low-cost single, dual, and quad comparators without  
shutdown, respectively. The comparators’ 4mV of built-  
in hysteresis provides noise immunity and prevents  
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, virtually  
eliminating power-supply glitches.  
o No Phase Reversal for Overdriven Inputs  
o Space-Saving Packages
