Description

The LTC®1440/LTC1441/LTC1442 are ultralow power single and dual comparators with built-in references. The comparators feature less than 3.7mA supply current over temperature (LTC1440), a 1.182V ±1% reference, programmable hysteresis (LTC1440/LTC1442) and TTL/CMOS outputs that sink and source current. The reference output can drive a bypass capacitor of up to 0.01mF without oscillation.

The comparators of LTC1440/LTC1441/LTC1442 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 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 of LTC1440/LTC1441/LTC1442 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 and MSOP packages. The LTC1441/LTC1442 are available in 8-pin PDIP and SO packages.
