FDC1004DSCR

Sensor

capacitance-to-digital converter4-channelI2CWSON-10capacitive sensing

FDC1004DSCR is a 4-channel capacitance-to-digital converter for grounded capacitive sensors. It supports ±15 pF conversion range, programmable offset cancellation, I2C control, and active shielding.

Best for

  • Multi-channel capacitive sensing
  • Non-contact liquid-level sensing
  • Proximity and gesture sensing

Avoid if

  • The sensor is not referenced to the intended system ground
  • The capacitance difference in a differential measurement exceeds ±15 pF

Check before use

  • Set CAPDAC for large single-ended sensor offsets
  • Use the appropriate SHLD output for sensor trace or cable shielding
  • Verify the WSON footprint and exposed-pad grounding
