General Overview
The AS5215 is a redundant contactless rotary encoder
sensor for accurate angular measurement over a full turn
of 360º and over an extended ambient temperature range
of - 40ºC…+150ºC.
Based on an integrated Hall element array, the angular
position of a simple two-pole magnet is translated into
analog output voltages. The angle information is provided
by means of buffered sine and cosine voltages. This
approach gives maximum flexibility in system design, as
it can be directly integrated into existing architectures and
optimized for various applications in terms of speed and
accuracy.
An SSI Interface is implemented for signal path
configurations, as well as a one time programmable
register block (OTP), which allows the customer to adjust
the signal path gain for different mechanical constraints
and magnetic fields.

The AS5215 Demoboard
The AS5215 demoboard is a complete rotary encoder system with built-in microcontroller, USB interface, and graphical
LCD display. The board is USB powered or externally supplied with a 9V battery for standalone operation.

Operating the AS5215 Demoboard
The AS5215 demoboard can be used in several ways:
•
As standalone unit supplied by a 9V battery
Connect a 9V battery to the battery connector on the top right side of the board. No other connections are
required.
•
As standalone unit supplied by an USB port
Connect the demoboard to a PC using a USB/USB cable (included in demoboard shipment). The board is
supplied by the 5V supply of the USB port. No other connections are required.
•
As input device for the AS5000 Programmer GUI software
This configuration uses the same USB hardware connection as mentioned above, but additionally the AS5000
Programmer GUI software is running. The LCD display will be turned off and the Angle/Sine/Cosine value will
be displayed on the PC screen.
