General Description
The MAX9039–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.
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 rail-to-rail, push-pull output stages that sink and
source up to 8mA. The propagation delay is 400ns,
even with the low-operating supply current.
The reference output voltage is set to 1.23V in the
MAX9039, to 2.048V in the MAX9040–MAX9043, and 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 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.

can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder profiles recommended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection Packaging
Reflow. Preheating is required. Hand or wave soldering is not allowed.
