MAX9038–MAX9043/
MAX9050–MAX9053
Micropower, Single-Supply, UCSP/SOT23
Comparator + Precision Reference ICs
General Description
Features
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.
● Comparator + Precision Reference in UCSP/SOT23
● 2.5V to 5.5V Single-Supply Operation
(MAX9038–MAX9043)
● Low Supply Current (MAX9038/MAX9039/MAX9040/
MAX9041/MAX9050/MAX9051)
• 40μA Quiescent
• 50μA with 100kHz Switching
• Open-Drain Output MAX9038
● 400ns Propagation Delay
● Rail-to-Rail Inputs
● Rail-to-Rail Output Stage Sinks and Sources 8mA
● Internal ±3mV Hysteresis
● Voltage Reference Offers
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.
• ±0.4% (max) Initial Accuracy (A Grade)
• 6ppm/°C (typ) Temperature Coefficient (A Grade)
• Stable for 0 to 4.7nF Capacitive Loads

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.

Comparator + Precision Reference ICs
these body diodes become forward biased and begin to
conduct. Consequently, bias currents increase exponen-
tially as the input voltage exceeds the supply rails.
Detailed Description
The MAX9038–MAX9043 and MAX9050–MAX9053
feature single/dual, low-power, low-voltage compara-
tors and a precision voltage reference. They operate
from a single 2.5V to 5.5V (MAX903_/MAX904_) or
2.7V to 5.5V (MAX905_) supply. The single compa
rators with reference, (MAX9038/MAX9039/MAX9040/
MAX9041/MAX9050/MAX9051 consume only 40μA of
supply current, while the dual comparators with reference
(MAX9042/MAX9043/MAX9052/MAX9053) consume
only 55μA of supply current. Their common-mode input
range extends 0.25V beyond each rail. Internal hysteresis
ensures clean output switching, even with slow-moving
input signals.
Comparator Output Stage Circuitry
The comparators in these devices contain a unique out-
put stage capable of rail-to-rail operation with loads up to
8mA. Many comparators consume orders-of-magnitude
more current during switching than during steady-state
operation. However, with this family of comparators,
the supply current change during an output transition is
extremely small. The Typical Operating Characteristics
graph Supply Current vs. Switching Frequency shows
the minimal supply current increase as the output switch-
ing frequency approaches 1MHz. This characteristic
reduces the need for power-supply filter capacitors to
reduce glitches created by comparator switching cur-
rents. Another advantage realized in high-speed, battery-
powered applications is a substantial increase in battery
life. The MAX9038 is an opendrain output comparator
that can be used in logic-level translation or many other
applications where voltage level translation is important.
The output stage employs a unique design that minimizes
supply current surges while switching, virtually eliminating
the supply glitches typical of many other comparators.
Large internal output drivers allow rail-to-rail output swing
that can sink and source up to 8mA of current.
The precision reference uses a proprietary curvaturecorrec-
tion circuit and laser-trimmed thin-film resistors, resulting in
a temperature coefficient of less than 30ppm/°C over the
extended temperature range and initial accuracy of 0.4% (A
grade). The reference output voltage is set to 1.23V in the
MAX9038/MAX9039, 2.048V in the MAX9040–MAX9043,
and to 2.500V in the MAX9050–MAX9053.
Applications Information
Additional Hysteresis
These comparators have ±3mV internal hysteresis.
Additional hysteresis can be generated with two resistors
using positive feedback (Figure 1). Use the following pro-
cedure to calculate resistor values:
Comparator Input Stage Circuitry
The devices’ input common-mode range extends from
1) Calculate the trip points of the comparator using
these formulas:
(V
- 0.25V) to (V
+ 0.25V). These comparators may

operate at any differential input voltage within these limits.
Input bias current is typically 1.0pA if the input voltage is
between the supply rails. Comparator inputs are protected
from overvoltage by internal body diodes connected to the
supply rails. As the input voltage exceeds the supply rails,

Board Layout and Bypassing
V
Power-supply bypass capacitors are not typically needed,
but would be called for in cases where supply imped-
ance is high, supply leads are long, or excessive noise is
expected on the supply lines. Use 100nF bypass capaci-
tors under these conditions. Minimize signal trace lengths
to reduce stray capacitance.

The MAX9038/MAX9039/MAX904_/MAX905_ do not
require an output capacitor on REF for frequency stability.
They are stable for capacitive loads up to 4.7nF. However,
in applications where the load or the supply can experience
step changes, an output capacitor will reduce the amount
of overshoot (or undershoot) and assist the circuit’s tran-
sient response. When an application is not subject to tran-
sient conditions, the REF capacitor can be omitted.

Biasing for Data Recovery
and
Digital data is often embedded into a bandwidth- and
amplitude-limited analog path. Recovering the data can
be difficult. Figure 2 compares the input signal to a time-
averaged version of itself. This self-biases the threshold
to the average input voltage for optimal noise margin.
