Description

General part information

LTC1445 Series

The LTC1443/LTC1444/LTC1445 are ultralow power quad comparators with a built-in reference. The comparators feature less than 8.5μA supply current over temperature, an internal reference (1.182V ±1% for LTC1443 or 1.221V ±1% for LTC1444/LTC1445), programmable hysteresis (LTC1444/LTC1445) and TTL/CMOS output (LTC1443/ LTC1445) that sinks and sources current (open-drain output for LTC1444). 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 (LTC1443). Comparator hysteresis is easily programmable using two resistors and the HYST pin (LTC1444/LTC1445). Each comparator’s input operates from the negative supply to within 1.3V of the positive supply. The LTC1443/LTC1445 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.The LTC1443/LTC1444/LTC1445 are available in the 16-pin SO, PDIP and DFN packages.ApplicationsBattery-Powered System MonitoringThreshold DetectorsWindow ComparatorsOscillator Circuits
