    Products Detail

    The QT301 is a digital burst mode charge-transfer (QT) capacitance-to-analog converter (CAC) with PWM output designed for fluid level sensing and distance gauging. It features end-to-end calibration via CAL pins, spread-spectrum burst modulation for noise rejection, and requires only one external sample capacitor. The device operates on demand via Sync input and stores calibration data in internal EEPROM.

    Key Features

    • Patented charge-transfer conversion method
    • Sub-ranging Direct-to-Analog conversion
    • Rescaleable PWM with wide dynamic range
    • End-to-end calibration via CAL pins
    • 100 kHz PWM
    • Spread spectrum acquisition bursts for low noise
    • Sample on demand via Sync pin
    • Only one external sample capacitor
    • Internal EEPROM for calibration storage
    • Burst mode reduces RF emissions and EMI susceptibility

    Application scenarios

    • Fluid level sensors
    • Moisture detection
    • Transducer driver
    • Proximity sensors
    • Position sensing
    • Material sensors
    • Distance sensors
    • Transducer amplifiers for pressure and humidity sensing
