The comparators feature less than 5.7μA supply current over temperature, a 1.182V ±1% reference, programmable hysteresis and open-drain outputs that sink current. The reference output can drive a bypass capacitor of up to 0.01μF without oscillation. The LTC1841 operates from a single 2V to 11V supply or a dual ±1V to ±5.5V supply. The LTC1842/LTC1843 operate from a single 2.5V to 11V supply or a dual ?1.25V to ±5.5V supply. The LTC1842/LTC1843 hysteresis is easily programmed by using two resistors and the HYST pin. The comparators? input operates from the negative supply to within 1.3V of the positive supply. The comparators? output stage can typically sink greater than 20mA. By eliminating the cross-conduction current that normally happens when the comparators change logic states, power supply glitches are eliminated. The LTC1841/LTC1842/LTC1843 are available in SO-8 packages.
