Linear Hall-Effect Sensor IC with Analog Output
Application Note
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 ...
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.
Joysticks are widely used human-machine interfaces (HMI) that simultaneously report information on direction and amplitude. This document explains how to implement a 2D or 3D magnetic sensor to obtain a joystick with well-defined behavior.

P0173 - As consumers find new ways to outfit their living spaces with simple-to-use smart home and Internet of Things (IoT) products, they may be unaware of certain vulnerabilities and security features.
AN296200 - This application note presents a modified solution to magnetic sensing in long stroke applications. Through the incorporation of a microcontroller, a lower cost solution can be realized with fewer linear sensors than previously existing arc tangent solutions.
This application note describes the mathematics to convert the analog sine/cosine outputs of the A33230 into an angular position.
AN296108 - This application note provides a description of the Allegro implementation of the SENT protocol, which includes extensions developed by Allegro to enhance the information carrying dimensions of the output from the Allegro sensor IC to the vehicle electronic control units (ECU).
AN296227 - Implementing controller functions through non-contact solutions provides both performance and reliability advantages over typical contact-based input methods.
AN296121 - This application note provides information on how to use A1342 customer-adjustable compensation parameters to reduce systems errors as a result of ambient temperature changes.
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.
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.
