Description

The LDC1314's unique inductive sensing capability is used to implement a contactless rotational position sensing solution that is accurate to 1 degree. It uses standard PCB technology and easily manufactured components to implement a low cost solution.

This reference design uses the LDC1314.  This reference design can also be used with LDC1312, LDC1612 and LDC1614.

Features
  • Absolute angle sensing with 1 degree accuracy
  • 0.1 degree resolution
  • Does not use magnets
  • Temperature stable
  • Automatically corrects for z-axis wobble
