LTC1440/LTC1441/LTC1442

Ultralow Power Single/Dual

Comparator with Reference

DESCRIPTIO

FEATURES

The LTC^®1440/LTC1441/LTC1442 are ultralow power

single and dual comparators with built-in references. The

comparators feature less than 3.7µA supply current over

temperature (LTC1440), a 1.182V ±1% reference, pro-

grammablehysteresis(LTC1440/LTC1442)andTTL/CMOS

outputsthatsinkandsourcecurrent. Thereferenceoutput

can drive a bypass capacitor of up to 0.01µF without

oscillation.

3mm x 3mm x 0.75mm DFN Package (LTC1440)

The comparators operate from a single 2V to 11V supply

or a dual ±1V to ±5.5V supply (LTC1440). Comparator

hysteresis is easily programmed by using two resistors

andtheHYSTpin(LTC1440/LTC1442).Eachcomparator’s

input operates from the negative supply to within 1.3V of

the positive supply. The comparator output stage can

continuously source up to 40mA. By eliminating the

cross-conductingcurrentthatnormallyhappenswhenthe

comparatorchangeslogicstates,thepowersupplyglitches

are eliminated.
