Evaluation Kit Operation Manual
1 General Description
This document describes the features and operation of the
AS5304/-06 Evaluation Kit.
The AS5304 and AS5306 are Hall-sensor based encoder
chips suitable for high resolution measurement of linear
motion or off-axis rotary motion using multipole magnetic
strips or rings.
Both AS5304 and AS5306 are pin-compatible, the main
difference is the resolution. The AS5304 has a resolution of
25µm per step, using multi-pole magnets with 2mm pole
length and the AS5306 has a resolution of 15µm per step,
using multi-pole magnets with 1.2mm pole length.
1.1
The AS5304/-06 evaluation kit contains the following parts:
Revision A.00
Fig. 1: AS5304 Evaluation Kit with 2.0mm pole length magnet
Evaluation kit contents
An AS5304/-06-AB adapterboard populated with
either an AS5304A or AS5306A chip
An AS5000-CT LCD counter module
A plexiglass bar with a multipole magnetic strip,
either with 2.0mm or 1.2mm pole length, matching
the installed chip
a fixture to hold the magnetic bar
a 9V battery

EVALUATION KIT OPERATION MANUAL
2 Features
The AS5304A or AS5306A mounted on the adapterboard
are located in an exposed area of the PCB to allow the
placement of either a fixture containing a sliding multipole
magnetic bar over the IC.
Holes in the PCB match with pins on the fixture to hold the
magnet strip in place when it is attached to the AS5304/-06
adapterboard.

... This unwanted behavior can be avoided in customer designs by using counters that accept an edge triggered reset. On the evaluation kit, it can be avoided by setting the jumper to AC decoupled connection, which generates a short reset pulse (active low) from the rising edge of the Index output. www.austriamicrosystems.com index output and reset ...
