AS5304 / AS5306
Integrated Hall ICs for
Linear and Off-Axis Rotary Motion Detection

General Description

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.
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).
A single index pulse is generated once for every pole pair
at the Index output.
Using, for example, a 32pole-pair magnetic ring, the
AS5304/AS5306 can provide a resolution of 1280
pulses/rev, which is equivalent to 5120 positions/rev or

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).
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
TSSOP package and specified for an operating ambient
