Micropower, Single-Supply, UCSP/SOT23

Comparator + Precision Reference ICs

General Description

Features

ꢀ Comparator + Precision Reference in UCSP/SOT23

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.

ꢀ 2.5V to 5.5V Single-Supply Operation

(MAX9039–MAX9043)

ꢀ Low Supply Current (MAX9039/MAX9040/

MAX9041/MAX9050/MAX9051)

40µA Quiescent

50µA with 100kHz Switching

ꢀ 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.

ꢀ Voltage Reference Offers:

0.4% (max) Initial Accuracy (A grade)

6ppm/°C (typ) Temperature Coefficient (A grade)

Stable for 0 to 4.7nF Capacitive Loads

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.
