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
Non-Contact Based Controller Solutions
AN296227 - Implementing controller functions through non-contact solutions provides both performance and reliability advantages over typical contact-based input methods.
Application Note
Linearization and Two-Point Programming on the A31100 and A31102
AN296213 - This application note highlights the procedure for calculating the magnetic field compensation parameters through two-point programming and calculating the linearization coefficients using our available software tools with the intention of providing an easy-to-use guide to programming these sensor ICs.
Application Note
Output Protocols for Angle and Linear Position Sensors
AN296191 - This application note describes working principles, lists advantages and limitations, outlines communication rates/delays, and defines error reporting tactics for digital and analog protocols used in angle and linear position sensing.
Application Note
Linear Hall-Effect Sensor ICs
AN27702 - Linear sensor ICs are designed to respond to a wide range of positive or negative magnetic fields. Critical to the performance of linear ICs is their sensitivity and linearity over their specified operating temperature range.
