A1337 Datasheet Hall-effect Angle Sensor

Manufacturer: Allegro MicroSystems

Overview: A1337 Precision, Hall-Effect Angle Sensor IC with SPI and SENT.

General Description

The A1337 is a 0° to 360° angle sensor IC that provides contactless high-resolution angular position data based on magnetic circular vertical Hall (CVH) technology.

It has a system-on-chip (SoC) architecture that includes: a CVH front end, digital signal processing, digital SPI, and SENT outputs.

It also includes on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, for flexible end-of-line programming of calibration and configuration parameters.

Key Features

  • Contactless 0° to 360° angle sensor IC, for angular position and rotation direction measurement.
  • 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 rate) configurable between 25 and 3200 μs through EEPROM programming.
  • Capable of sensing magnetic rotational speeds up to 7600 rpm, and up.
