The is an ultra-low power quad Comparator with a built-in reference. The comparator feature less than 8.5µA supply current over-temperature, an internal reference and TTL/CMOS output that sinks and sources current. The reference output can drive a bypass capacitor of up to 0.01µF without oscillation. The comparator operates from a single 2 to 11V supply or a dual ±1 to ±5.5V supply. The comparator input operates from the negative supply to within 1.3V of the positive supply. Comparator hysteresis is easily programmable using two resistors and the HYST pin. 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, power supply glitches are eliminated.
