General Description
The MAX9038–MAX9043 and MAX9050–MAX9053 fea-
ture combinations of low-power comparators and preci-
sion 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 switch-
ing, even with slow-moving input signals. The output
stage features a unique design that limits supply cur-
rent 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 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-cor-
rection circuit and laser-trimmed thin-film resistors.
These series-mode references can sink or source up to
500µA of load current.
