MAX9038–MAX9043/
MAX9050–MAX9053
Micropower, Single-Supply, UCSP/SOT23
Comparator + Precision Reference ICs
General Description
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.
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.
The reference output voltage is set to 1.23V in the MAX9038/
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 (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.

Note 1: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device 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.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
