AS5304 / AS5306 - Demo Kit User Manual
Position Sensor Connector
The Position connector allows the user to monitor the ABI signals from the AS5304/ AS5306 as
well as to connect this demoboard to an external sensor (see below,
Sensor) as shown in

Analog Output
If the on-board sensor is used for the measurements the Analog Output (AO) provides an analog
output voltage that represents the Automatic Gain Control of the position sensor signal control
loop. This output is used to monitor the magnetic field strength respectively the air gap between
sensor and multipole magnet strip. For more details refer to the position sensor datasheet.

Connection of an external Sensor
With the jumpers, the onboard position sensor can be disconnected to use an external position
sensor. Follow the instructions below to use an external position sensor.
(1) Disconnect the power supply of the demoboard by unplugging the USB cable.
(2) Disconnect the onboard position sensor by removing P1, P2, P3, and P4 jumpers. See
Figure
7.
(3) As the onboard position sensor is disconnected, connect an external position sensor. For
example an AS5304 / AS5306 adapter board can be used. See
The AS5304 / AS5306 AB adapter board is optional and not included in the demo kit.
