Maxim MAX9052AESA, MAX9051AESA, MAX9051AEUT-T, MAX9051BESA, MAX9043AEUB Datasheet

General Description

The MAX9040–MAX9043 and MAX9050–MAX9053 fea­ture combinations of low-power comparators and a pre­cision 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-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
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 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 laser­trimmed thin-film resistors. The series-mode references
can sink or source up to 500µA of load current.
