　　the als31300 3dmag?position sensor ic provides a 12-bit digital value corresponding to the magnetic field measured in each of the x, y, and z axes. the als31300 is preconfigured for use in 3d sensing applications for head-on linear motion, slide-by position sensing, and rotation angle measurements. the als31300 is also offered in joystick mode, including a low gain option for the z axis channel. this feature enables the use of a back-bias magnet to provide return-to-zero force instead of traditional spring-based solutions.

　　three different factory-programmed sensitivity ranges are available:±500 g,±1000 g, and±2000 g.

　　the i2c address of the als31300 can be set either by external resistors (16 unique addresses) or programmed into eeprom via i2c (127 unique addresses), allowing for multiple devices on the same bus. the als31300 also includes 78 bits of user eeprom.

　　power management of the als31300 is highly configurable, allowing for system-level optimization of supply current and performance. sleep mode consumes just 14 na (typical), making the als31300 well suited for portable, battery-operated

　　applications.

　　the als31300 is supplied in a 3 mm×3 mm ×0.8 mm, 10-contact dfn package (“ej”). this small footprint package is lead (pb) free, with 100 % matte-tin leadframe plating.
