AS5304 / AS5306  
PRELIMINARY DATA SHEET  
Integrated Hall ICs for  
Linear and Off-Axis Rotary Motion Detection  
1 General Description  
2 Benefits  
The AS5304/AS5306 are single-chip IC’s with integrated  
Hall elements for measuring linear or rotary motion using  
multi-pole magnetic strips or rings.  
Complete system-on-chip  
High reliability due to non-contact sensing  
Suitable for the use in harsh environments  
Robust against external magnetic stray fields  
This allows the usage of the AS5304/AS5306 in  
applications where the Sensor IC cannot be mounted at the  
end of a rotating device (e.g. at hollow shafts). 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 of up to 20 meters/sec (AS5304) or 12 meters/sec  
(AS5306).  
3 Key Features  
High speed, up to 20m/s (AS5304)  
12m/s (AS5306)  
Magnetic pole pair length: 4mm (AS5304) or  
2.4mm (AS5306)  
A single index pulse is generated once for every pole pair  
at the Index output.  
Resolution: 25µm (AS5304) or 15µm (AS5306)  
40 pulses / 160 positions per magnetic period.  
1 index pulse per pole pair  
Using, for example,  
a
32pole-pair magnetic ring, the  
resolution of 1280  
AS5304/AS5306 can provide  
a
pulses/rev, which is equivalent to 5120 positions/rev or  
12.3bit. The maximum speed at this configuration is 9375  
rpm.  
Linear movement measurement using multi-pole  
magnetic strips  
The pole pair length is 4mm (2mm north pole / 2mm south  
pole) for the AS5304, and 2.4mm (1.2mm north pole /  
1.2mm south pole) for the AS5306. The chip accepts a  
magnetic field strength down to 5mT (peak).  
Circular off-axis movement measurement using multi-  
pole magnetic rings  
4.5 to 5.5V operating voltage  
Magnetic field strength indicator, magnetic field alarm  
for end-of-strip or missing magnet  
Both chips are available with push-pull outputs  
(AS530xA) or with open drain outputs (AS530xB).  
The AS5304/AS5306 are available in  
a small 20-pin  
4 Applications  
The AS5304/AS5306 are ideal for high speed linear motion  
and off-axis rotation measurement in applications such as  
TSSOP package and specified for an operating ambient  
temperature of -40° to +125°C.  
electrical motors  
X-Y-stages  
rotation knobs
