Micropower, Single-Supply,

SOT23 Comparator + Precision Reference ICs

General Description

Features

The MAX9040–MAX9043 and MAX9050–MAX9053 fea-

ture combinations of low-power comparators and a pre-

cision voltage reference. Their operating voltage range

makes them ideal for both +3V and +5V systems. The

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 a reference,

while consuming only 55µA of supply current. Low-volt-

age operation and low supply current make these

devices ideal for battery-operated systems.

ꢀ 400ns Propagation Delay

ꢀ Rail-to-Rail Inputs

ꢀ Rail-to-Rail Output Stage Sinks and Sources 8mA

ꢀ Internal 3mV Hysteresis

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 2.048V in the

MAX9040–MAX9043 and to 2.500V in the MAX9050–

MAX9053. These devices 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 and

100ppm/°C tempco. The voltage reference features a

proprietary curvature-correction circuit and laser-

trimmed thin-film resistors. The series-mode references

can sink or source up to 500µA of load current.
