Sensor

FDC2214-Q1capacitance-to-digital converter28-bitI2CAEC-Q100WQFN-16

FDC2214-Q1 is a 4-channel, 28-bit LC-resonant capacitance-to-digital converter for EMI-resistant capacitive sensing in automotive and industrial designs.

Best for

  • Multi-channel capacitive sensing
  • Automotive proximity and environmental sensing
  • LC-resonant sensors requiring low noise

Avoid if

  • A simple switched-capacitance touch controller is sufficient
  • The design cannot accommodate external LC tank components
  • Sensor resonance cannot be kept within the supported frequency range

Check before use

  • Validate inductor self-resonant frequency margin
  • Configure FIN and FREF dividers for the sensor frequency
  • Measure sensor amplitude and set IDRIVE accordingly
  • Verify active-channel timing when auto-scanning
