LDC0851EVM - High Accuracy Inductive Switch with Stacked Coils Evaluation Module



  • 1.8V - 3.3 V
  • < 5% Switching Accuracy
  • Push/Pull Output
  • Temperature and other environmental variation compensation

Texas Instruments  LDC0851EVM

The LDC0851EVM (Evaluation Module) demonstrates the use of inductive sensing technology to accurately detect the presence of a conductive target object passing a fixed threshold.  The module includes a perforated and interchangeable 4-layer PCB where both the sensing coil as well as the reference coil are stacked for reduced system size.  The presence of a conductive object passing the fixed threshold is indicated by a green LED and therefore no MCU is needed.  A resistive potentiometer can adjust the switching threshold easily for flexibility and quick system prototyping.
