The LTC1843IS8#TRPBF from Analog Devices is an ultralow power dual comparator featuring a built-in 1.182V ±1% reference. It consumes less than 5.7 μA supply current over temperature, with a typical quiescent current of 3.5 μA.
This comparator features programmable hysteresis and open-drain outputs that can sink current. The reference output can drive a bypass capacitor up to 0.01μF without oscillation. The input voltage range includes the negative supply, and the output stage can typically sink greater than 20mA. Power supply glitches are eliminated by preventing cross-conduction current during logic state changes.
The LTC1843IS8#TRPBF operates from a single 2.5V to 11V supply or a dual ±1.25V to ±5.5V supply. It has a propagation delay of 12μs with 10mV overdrive. The device is available in an 8-SOIC package suitable for surface mounting.
Applications include battery-powered system monitoring, threshold detectors, window comparators, and oscillator circuits.
The typical supply current is 3.5μA at 25°C.
The reference voltage is 1.182V with a tolerance of ±1%.
The maximum propagation delay is 12μs with 10mV overdrive.
The operating temperature range is -40°C to 85°C.
It features open-drain outputs.
It is supplied in an 8-SOIC package.
