Description
General part information
LTC1440 Series
The LTC1440 is an ultralow power comparator with a built-in voltage reference. The comparator features less than 4.0µA supply current over temperature. The internal reference is 1.182V with ±1% accuracy. The LTC1440 has 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 comparators operate from a single 2V to 11V supply or a dual ±1V to ±5.5V supply. Comparator hysteresis is easily programmed by using two resistors and the HYST pin. 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 LTC1440 is available in a 3mm × 3mm × 0.75mm DFN package, as well as 8-pin PDIP and SO-8.ApplicationsBattery-Powered System MonitoringThreshold DetectorsWindow ComparatorsOscillator Circuits
