AH4930
3D MAGNETIC LINEAR
HALL SENSOR WITH I2C INTERFACE Description Pin Assignments The AH4930 3D magnetic chip is a miniature monolithic sensor IC
sensitive to the three orthogonal components of the flux density applied
to the IC. On-chip integrated temperature sensor data is available for
system functions such as junction temperature indication and
temperature compensation of magnetic field measurement. A precision
analog signal-path along with integrated ADC digitizes the measured
analog magnetic field values, and this allows the AH4930 with the
correct magnetic circuit to decode the absolute position of any moving
magnet. With its magnetic field detection in x, y, and z-direction the
sensor reliably measures three-dimensional, linear and rotation
movements. (Top View) SCL/INT The AH4930 measurement data can be read over I2C bus. The sensor
is runtime programmable and offers on-chip temperature
compensation of the measured units. The selectable power mode
control unit enables micro-power and continuous measurement
functionality. Applications include joysticks, control elements (white
goods, multifunction knops), or electric meters (anti-tampering) and
any other application that requires accurate angular measurements or
low power consumptions. GND 2 GND 3 Applications •
