TIDA-00828 Reference Design

Texas Instruments

Inductive Sensing 32-Position Encoder Knob Reference Design using the LDC0851

Description

An inductive sensing based incremental encoder knob design can provide a robust and low-cost interface for control inputs.  It can reliably operate in environments which have dirt: moisture: or oil which would pose issues for alternate sensing technologies. This solution requires no magnets.

Features
  • High reliability: contactless: encoder implementation suitable for dirty: wet: and other challenging environmentsScalable to support multiples of 4 positions/rotationMinimal MCU requirementsNo permanent magnets required; operates effectively even with magnetic or electrical environmental interference
