14-Bit Absolute Angle Hall Encoder

iC-MHM is a position sensor with four Hall sensors for scanning a diametral permanent magnet.

The Hall sensors provide differential sine/cosine signals which can be calibrated with respect to amplitude ratio and offset. The integrated sine-to-digital converter is configurable up to 4 096 angular increments per rotation.

External multiturn sensor data can be read in and synchronized. External access is provided via the BiSS interface with BiSS C or SSI protocol and the integrated line drivers.
