... Instead, the AS5304/AS5306 are mounted off-axis underneath a multi- pole magnetized ring or strip and provides a quadrature incremental output with 40 pulses per pole period at speeds meters/sec (AS5304 meters/sec (AS5306). An single index pulse is generated once for every pole pair at the Index output. ...

... Functional Description 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 60mT at the chip surface. ...

... The magnetic field warning indicator (see 7.1.2) together with the index pulse can be used to indicate a unique home position on a magnetic strip: 1. First the AS5304/06 moves to the end of the strip, until a magnetic field warning is displayed (Index = high, A=B=low) 2. Then, the AS5304/06 moves back towards the strip until the first index position is reached (note: an index position is generated once for every pole pair indicated with : Index = high, A=B= high) ...

... The INL (integral non-linearity) is the deviation between indicated position and actual position better than 1LSB for both AS5304 and AS5305, assuming an ideal magnet. Pole length variations and imperfections of the magnet material, which lead to a non-sinusoidal magnetic field will attribute to additional linearity errors. ...

... Figure 9: AO output versus AGC, magnetic field strength, magnet-to-IC gap 8.1 Resolution and maximum rotating speed When using the AS5304/ off-axis rotary application, a multi-pole ring magnet must be used. Resolution, diameter and maximum speed depend on the number of pole pairs on the ring. 8.1.1 Resolution The angular resolution increases linearly with the number of pole pairs ...

... For linear motion sensing, a multi-pole strip using equally spaced north and south poles is used. The pole length is again fixed at 2.0mm for the AS5304 and 1.2mm for the AS5306. As shown in 8.1.3 above, the sensors can process up to 5000 pole pairs per second, so the maximum travelling speed is: ...
