A1334 - Micro Power Hall-Effect Angle Sensor

General Description

The A1334 is a 360° angle sensor IC that provides contactless high-resolution angular position information based on magnetic Circular Vertical Hall (CVH) technology.

It has a system-onchip (SoC) architecture that includes: a CVH front end, digital signal processing, and a digital (SPI) output.

Key Features

  • Automotive AEC-Q100 qualified.
  • Contactless 0° to 360° angle sensor IC, for angular position, rotational speed, and direction measurement.
  • Available with either a single die or dual independent die housed within a single package.
  • Circular Vertical Hall (CVH) technology provides a single-channel sensor system, with air-gap independence.
  • 12-bit resolution possible in low RPM mode, 10-bit resolution in high RPM mode.
  • Angle Refresh Rate (output r.
