The LTC1442 is an ultralow power dual comparator with a built-in voltage reference. The comparators feature less than 5.7µA supply current over temperature, a 1.182V ±1% reference, programmable hysteresis and TTL/CMOS outputs that sink and source current. The voltage 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 to ±5.5V supply. Comparator hysteresis is easily programmed by using two resistors and the HYST pin. 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 LTC1442 is available in an 8-pin PDIP and SO package.
