A31301 Datasheet 3d Linear Hall-effect Sensor

Manufacturer: Allegro MicroSystems

Overview: A31301 3D Linear Hall-Effect Sensor with SPI, I2C Interfaces, and Advanced Low-Power.

General Description

The A31301 three-axis Hall-effect sensor IC is a flexible magnetic sensor capable of measuring the applied flux density in any 1, 2, or 3 axes as well as calculating the angle in up to any two user defined planes.

The A31301 comes in three standard field configurations of ±600 G, ±1400 G, or ±2000 G.

Additionally, the devices are available preconfigured for SPI or I2C.

Key Features

  • Flexible operating modes.
  • Can measure input in any 1, 2, or 3 axes.
  • 15-bit angle output from any selectable 2-axes plane.
  • Low RMS angle noise for high system resolution.
  • SPI and I2C interfaces for easy system integration.
  • Up to 10 MHz SPI and 1 MHz I2C.
  • Ideal for battery-powered, low-voltage.
