The LTC1842 is an ultralow power dual comparator with a built-in reference. 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 LTC1842 operate from a single 2.5V to 11V supply or a dual ±1.25V to ±5.5V supply. Hysteresis is easily programmed by using two resistors and the HYST pin. The comparator inputs operate from the negative supply to within 1.3V of the positive supply. The comparator outputs 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 LTC1842 is available in an SO-8 package.
