The LTC1841 is an ultralow power dual comparator featuring less than 5.7µA supply current over temperature, a 1.182V ±1% reference, programmable hysteresis and open-drain outputs that sink current. The reference output can drive a bypass capacitor of up to 0.01µF without oscillation.
The LTC1841 operates from a single 2V to 11V supply or a dual ±1V to ±5.5V supply. The comparator inputs operate from the negative supply to within 1.3V of the positive supply. The comparator outputs can typically sink greater than 20mA. By eliminating the cross-conduction current that normally happens when the comparators change logic states, power supply glitches are eliminated.
The LTC1841 are available in an SO-8 package.
Applications
- Battery-Powered System Monitoring
