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.
