Key Features
- Rail-to-rail input capability, allowing the input signal range to extend up to the supply voltage range, including 200 mV beyond the supply rails.
- Low power consumption: the quad comparator consumes only 26.8 µA to 36.8 µA of supply current.
- Open-drain output stage requiring an external pull-up resistor to achieve the desired logic high voltage level.
- UnderVoltage Lockout (UVLO) feature to ensure the comparator output remains low until the supply voltage reaches a safe operating level.
- High common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) for robust operation in noisy environments.
Applications
- Battery management and monitoring systems.
- Power supply detection and monitoring.
- Window comparators and threshold detectors/discriminators.
- Microprocessor systems requiring low power and high accuracy comparators.
