A1333 - Hall-Effect Angle Sensor

General Description

The A1333 is a 360° angle sensor IC that provides contactless high-resolution angular position data based on magnetic circular vertical Hall (CVH) technology.

Key Features

  • Contactless 0° to 360° angle sensor IC, for angular position, rotational speed, and direction measurement.
  • Capable of sensing magnet rotational speeds targeting 12-bit effective resolution with 900 G field.
  • Circular vertical Hall (CVH) technology provides a single-channel sensor system supporting operation across a wide range of air gaps.
  • Developed in accordance with ISO 26262 requirements for hardware product development for use in safetycritical.
