Data Acquisition

inductive sensinginductance-to-digital converter4-channelI2Ctouch buttonTSSOP-16low power

LDC3114QPWR is a 4-channel inductive sensing converter for LC-resonator touch buttons, conductive-target deflection measurement, and linear or rotary position sensing.

Best for

  • Multi-button inductive touch interfaces
  • Low-power conductive-target sensing
  • Raw inductive position data acquisition

Avoid if

  • The sensor cannot form a stable LC resonator within specified limits
  • A supply outside 1.71 V to 1.89 V is required

Check before use

  • LC resonant frequency and SENSORn_CONFIG range selection
  • Sensor Q of 5 to 30 and Rp of 350 Ω to 10 kΩ
  • COM capacitor placement and value
  • I2C address compatibility at 0x2A
