The LTC1443IS#PBF 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. The LTC1443 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.
