1 General Description
The AS5311 is a contactless high resolution magnetic linear encoder
for accurate linear motion and off-axis rotary sensing with a
resolution down to <0.5μm. It is a system-on-chip, combining
integrated Hall elements, analog front end and digital signal
processing on a single chip, packaged in a small 20-pin TSSOP
package.
A multi-pole magnetic strip or ring with a pole length of 1.0mm is
The AS5311 is available in a PB-free TSSOP-20 package and
qualified for an ambient temperature range from -40°C to +125°C.
2 Key Features
?? Two 12-bit digital absolute outputs:
- Serial interface and
- Pulse width modulated (PWM) output
required to sense the rotational or linear motion. The magnetic strip
is placed above the IC at a distance of typ. 0.3mm.
The absolute measurement provides instant indication of the magnet
position within one pole pair with a resolution of 488nm per step (12-
bit over 2.0mm). This digital data is available as a serial bit stream
and as a PWM signal.
?? Incremental output with Index

Furthermore, an incremental output is available with a resolution of

1.95μm per step. An index pulse is generated once for every pole
pair (once per 2.0mm).The travelling speed in incremental mode is
up to 650mm/second.

accepts multi-pole strip magnets as well as multi-pole ring magnets,
both radial and axial magnetized (see Figure 1 and Figure 3 ).
