Key Features

  • Rail-to-Rail Input: The comparator can operate with input signals that extend up to 200 mV beyond the supply rails, making it versatile for various applications.
  • Low Power Consumption: The ADCMP393 draws a minimal quiescent current of 26.8 µA to 36.8 µA, making it suitable for battery-powered systems.
  • Open-Drain Output: The comparator features an open-drain output stage that requires an external pull-up resistor to achieve the desired logic high voltage level.
  • Wide Operating Temperature Range: The device operates over a temperature range of -40°C to 125°C, ensuring reliability in diverse environmental conditions.
  • High CMRR and PSRR: The comparator has a high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR), ensuring stable operation despite variations in the supply voltage.

Applications

  • Battery Management/Monitoring: Ideal for monitoring battery levels and detecting under/overvoltage conditions in battery-powered systems.
  • Power Supply Detection: Can be used to detect power supply voltages and ensure proper system operation.
  • Window Comparators and Threshold Detectors/Discriminators: Suitable for applications requiring precise voltage comparisons and threshold detection.
  • Microprocessor Systems: Can be integrated into microprocessor systems for various monitoring and detection tasks.
