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 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.

Furthermore, an incremental output is available with a

resolution of 1.95 µm 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.

An internal voltage regulator allows the AS5311 to

operate at either 3.3 V or 5 V supplies.

Depending on the application the AS5311 accepts

multi-pole strip magnets as well as multi-pole ring

magnets, both radial and axial magnetized (see

Figure 1 and Figure 3).

The AS5311 is available in a Pb-free TSSOP-20

package and qualified for an ambient temperature

range from -40°C to +125°C.
