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

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-

grammable hysteresis (LTC1440/LTC1442) and TTL/CMOS

outputs that sink and source current. The reference output

can drive a bypass capacitor of up to 0.01µF without

oscillation.

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

or a dual

±1V

±5.5V

supply (LTC1440). Comparator

hysteresis is easily programmed by using two resistors

and the HYST pin (LTC1440/LTC1442). Each comparator’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-conducting current that normally happens when the

comparator changes logic states, the power supply glitches

are eliminated.

The LTC1440 is available in 8-pin PDIP, SO, MSOP and

DFN packages. The LTC1441/LTC1442 are available in

8-pin PDIP and SO packages.
