LTC1540CS8#PBF Datasheet PDF - Linear Technology

The LTC1540CS8#PBF is an ultralow nano-power single Comparator with built-in reference. The comparator features include less than 0.6µA supply current over the commercial temperature range, a 1.182V±2% reference, programmable hysteresis and TTL/CMOS outputs that sink and source 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. Comparator hysteresis is easily programmed by using two resistors and the HYST pin. The comparator 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 occur when the comparator changes logic states, power supply glitches are eliminated.
