Description
iC-Haus iC-TW39
The iC-Haus iC-TW39 is a very compact TMR-based system-on-chip solution for 360-degree absolute angle sensing in the end-of-shaft position. The sensor signal is resolved by a high-resolution interpolator, featuring resolution-enhancing digital filtering and automatic signal error correction.
