General Description
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 out-
puts, with a common-mode input voltage range that
extends 250mV beyond the supply rails. Input bias cur-
rent is typically 1.0pA, and input offset voltage is typi-
cally 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 sup-
ply 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.

Note 2: All devices are 100% production tested at TA = +25°C. Limits over the extended temperature range are guaranteed by
design.
Note 3: Supply voltage range guaranteed by PSRR test on comparator and line regulation of REF.
Note 4: VOS is defined as the center of the input-referred hysteresis band.
Note 5: For the comparators with the inverting input (IN-) uncommitted.
Note 6: Input bias current is the average of the inverting and noninverting input bias currents.
Note 7: Not production tested. Guaranteed by design.
Note 8: Guaranteed by CMRR test.
Note 9: VOVERDRIVE is beyond the offset and hysteresis determined trip point.
Note 10: Temperature coefficient is measured by the box method; i.e., the maximum ∆VREF is divided by the maximum ∆T.
Note 11: Thermal hysteresis is defined as the change in VREF at +25°C before and after cycling the device from TMIN to TMAX.
