This reference design demonstrates a high-resolution, absolute inductive angle encoder. A rotating conductive target printed circuit board (PCB) forms part of the design. The stationary PCB includes excitation and Nonius receiver coils as well as dual contactless inductive sensor front-ends with an inductor-capacitor (LC) oscillator and sine-cosine interfaces. An Arm® Cortex®-M0 microcontroller (MCU) with 4MSPS analog-to-digital converters (ADCs) calculates the absolute angle.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
