The LTC1441 is an ultralow power dual comparator, featuring less than 5.7µA supply current over temperature. The TTL/CMOS outputs both sink and source current. The comparators operate from a single 2V to 11V supply or a dual ±1V to ±5.5V supply. Each comparator’s 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 happens when the comparator changes logic states, the power supply glitches are eliminated. The LTC1441 is available in an 8-pin PDIP and SO package.
