AS5304/AS5306 Integrated Hall IC for linear and off-axis rotary motion detection
5
The AS5304/AS5306 require a multi-pole magnetic strip or ring with a pole length of 2mm (4mm pole pair length) on the
AS5304, and a pole length of 1.2mm (2.4mm pole pair length) on the AS5306. The magnetic field strength of the multi-pole
magnet should be in the range of 5 to 60mT at the chip surface.
The Hall elements on the AS5304/AS5306 are arranged in a linear array.
By moving the multi-pole magnet over the Hall array, a sinusoidal signal (SIN) is generated internally. With proper configuration
of the Hall elements, a second 90° phase shifted sinusoidal signal (COS) is obtained. Using an interpolation circuit, the length
of a pole pair is divided into 160 positions and further decoded into 40 quadrature pulses.
An Automatic Gain Control provides a large dynamic input range of the magnetic field.
An Analog output pin (AO) provides an analog voltage that changes with the strength of the magnetic field (see chapter 8).
