Application Note
This application note describes the mathematics to convert the analog sine/cosine outputs of the A33230 into an angular position.
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.
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.
AN296199 - This application note serves as a guide for using a two-point programming algorithm to calculate and program the values needed for short-stroke rotational position sensing with the A1330 angle sensor IC.
AN296166 - This application note is dedicated to short-stroke magnetic applications using Allegro angular position sensors based on circular vertical Hall (CVH) technology. Analyses and data used in this document are based on the A1335 angle sensor IC.

P0234: Electric power steering systems have become popular in automotive manufacturing, displacing their mechanical counterparts because they save space, weight, emissions, and reduce fit complexity.
Brochure
The Allegro A33230 Hall-effect position and angle sensor IC is the smallest 3D Sine/Cosine sensor currently available in the market.
AN296138 - The A1337 and A1338 are high-speed high-accuracy magnetic angle sensor ICs, ideal for motor position sensing. This application note provides a brief description of the internal signal processing delays of the A1337 and A1338 angle sensors.
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.
