The MAX9039–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 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 accura-
cy and 100ppm/°C tempco. The voltage references
feature a proprietary curvature-correction circuit and
laser-trimmed thin-film resistors. These series-mode ref-
erences can sink or source up to 500µA of load current.
