Application Note
Microcontroller-Based Linearization of Angular Sensor ICs
AN296160 - Magnetic angle sensors are often a good choice for fast, reliable, contactless measurement of the angular position of a system, especially in dirty environments where optical encoders may not be a good fit.
Application Note
Advanced On-Chip Linearization in the A1335 Angle Sensor IC
AN296127 - This document shows how magnetic-input-related errors in excess of ±20 degrees can be linearized by the A1335 to as low as ±0.3 degrees—roughly a 65× improvement.
