AS5040 8-bit Programmable Magnetic Rotary Encoder
AS5215
Programmable 360° Magnetic Angle Encoder with SINE &
COSINE Output Signals
1 General Description
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

Board description
The AS5115 adapter board is a simple circuit allowing test and evaluation the rotary encoder quickly without building a test fixture or
PCB. The connections of P1 are required for supplying, communicating and measuring. Connector JP2 provides access to PROG,
CM_2 and CM_1 (sine common mode voltage of device 1 and device 2 – pin12, pin14). The common mode voltages at all CM pins
provide the same level. Resistor R1, R2 (both 100k) are used as Pull-up on CS pins and the capacitors C1, C2 (both 2.2uF) are
placed between VDD and GND.

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.

Page 4: Operation Case
Figure 4: Operation cases with the adapter board The AS5215 provides analog Sine and Cosine outputs (JP1 – 11, 12, 13, 14). These outputs allow the user to perform the angle calculation by an external ADC + µC, e.g. to compute the angle with a high resolution. The signal lines should be kept as short as possible, longer lines should be shielded in order to achieve best noise performance. - Page 5 100nF capacitor (ceramic) and a 10µF capacitor. Programming of the AS5215 OTP memory does not require a dedicated programming hardware. The programming can be simply accomplished over the serial 3-wire interface (see Figure 5 – shown for device 1). For permanent programming (command PROG OTP, #25), a constant DC voltage of 8.0 –...
