AS5215
Programmable 360º Magnetic Angle Encoder with Buffered SINE &
COSINE Output Signals
www.austriamicrosystems.com/AS5215 Revision 1.4 1 - 2
Product Brief
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 integrated into existing architectures and
optimized for various applications in terms of speed and accuracy.
With two independent dies in one package, the device offers true
redundancy. Usually the bottom die, which is exposed to slightly less
magnetic field is employed for plausibility check.
An SSI Interface is implemented for signal path configuration as well
as a one time programmable register block (OTP), which allows the
customer to adjust the signal path gain to adjust for different
mechanical constraints and magnetic field.
