General Description
The AS5215 is a redundant, contactless rotary
encoder sensor for accurate angular measurement
over a full turn of 360° and over an extended ambient
temperature range of - 40°C to +150°C.
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
AS5215 offers true redundancy. The sensitivity of the
device, as well as the output mode, differential or sin-
gle ended, is programmable to keep highest system
flexibility.
An SSI Interface is implemented for signal path
configuration as well as a one time programmable
register block (OTP), which allows the customer
an adjustment of the signal path gain for different
mechanical constraints and magnetic fields.
The single die version AS5115 is available in an
SSOP 16 package.
