Product Overview
LTC1440IDD#PBF is an ultralow power comparator with a built-in reference. The comparator features less than 3.7µA supply current over temperature, a 1.182V ±1% reference, 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 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 occurs when the comparator changes logic states, power supply glitch is eliminated. Applications include battery-powered system monitoring, threshold detectors, window comparators, and oscillator circuits.
- Ultralow quiescent current is 2.1µA typ, reference output drives 0.01µF capacitor
- No crowbar current, 40mA continuous source current
- Comparator input offset voltage is ±3mV at VCM = 2.5V, TA = 25°C, V+ = 5V
- Input voltage range includes the negative supply
- TTL/CMOS compatible outputs
- Propagation delay is 15µs typ (COUT = 100pF, overdrive = 10mV, TA = 25°C, V+ = 5V)
- Common mode rejection ratio is 0.1mV/V typ (V– to V+ – 1.3V, TA = 25°C, V+ = 5V)
- Power supply rejection ratio is 0.1mV/V typ (V+ = 2.5V to 11V, TA = 25°C, V+ = 5V)
- Voltage noise is 100µVRMS typ (100Hz to 100KHz, TA = 25°C, V+ = 5V)
- 8 lead plastic DFN package, operating temperature range from -40°C to 85°C
