MAX9038–MAX9043/  
MAX9050–MAX9053  
Micropower, Single-Supply, UCSP/SOT23  
Comparator + Precision Reference ICs  
General Description  
Features  
The MAX9038–MAX9043 and MAX9050–MAX9053 feature  
combinations of low-power comparators and precision  
voltage references. Their operating voltage range makes  
them ideal for both 3V and 5V systems. The MAX9039/  
MAX9040/MAX9041/MAX9050/MAX9051 have a single  
comparator and reference consuming only 40μA of supply  
current. The MAX9042/MAX9043/MAX9052/MAX9053  
have dual comparators and one reference, and consume  
only 55μA of supply current. Low-voltage operation and  
low supply current make these devices ideal for battery-  
operated systems.  
● Comparator + Precision Reference in UCSP/SOT23  
● 2.5V to 5.5V Single-Supply Operation  
(MAX9038–MAX9043)  
● Low Supply Current (MAX9038/MAX9039/MAX9040/  
MAX9041/MAX9050/MAX9051)  
• 40μA Quiescent  
• 50μA with 100kHz Switching  
• Open-Drain Output MAX9038  
● 400ns Propagation Delay  
● Rail-to-Rail Inputs  
● Rail-to-Rail Output Stage Sinks and Sources 8mA  
● Internal ±3mV Hysteresis  
● Voltage Reference Offers  
The comparators feature rail-to-rail inputs and outputs,  
with a common-mode input voltage range that extends  
250mV beyond the supply rails. Input bias current is  
typically 1.0pA, and input offset voltage is typically 0.5mV.  
Internal hysteresis ensures clean output switching, even  
with slow-moving input signals. The output stage features  
a unique design that limits supply current surges while  
switching, virtually eliminating supply glitches typical of  
many other comparators. This design also minimizes  
overall power consumption under dynamic conditions.  
The comparator outputs have railto-rail, push-pull output  
stages except the MAX9038 has an open-drain output  
that sinks and sources up to 8mA. The propagation delay  
is 400ns, even with the low-operating supply current.  
• ±0.4% (max) Initial Accuracy (A Grade)  
• 6ppm/°C (typ) Temperature Coefficient (A Grade)  
• Stable for 0 to 4.7nF Capacitive Loads

to 2.500V in the MAX9050–MAX9053. The MAX9040–  
MAX9043 and the MAX9050–MAX9053 are offered in two  
grades: an A grade with 0.4% initial accuracy and 6ppm/°C  
tempco, and a B grade with 1% initial accuracy (except  
MAX9038/MAX9039 have an initial accuracy of ±0.4%)  
and 100ppm/°C tempco. The voltage references feature a  
proprietary curvature-correction circuit and laser-trimmed  
thin-film resistors. These series-mode references can sink  
or source up to 500μA of load current.
