AS5115
Programmable 360° Magnetic Angle Encoder with
SINE & COSINE Output Signals

1 General Overview

The AS5115 is a 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

2 The AS5115 Demoboard

The AS5115 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.

Demoboard v1.1 has additional pull-up resistors at the communication lines. The demoboard v1.2 has a new controller
(C8051F342) implemented and supports updating of the firmware via bootloader (please refer to AN5000-
60_FirmwareUpgrade).

3 Operating the AS5115 Demoboard

The AS5115 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.

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.
