AS5261
12-Bit Automotive Angle Position Sensor
1 General Description
The AS5261 is a contactless magnetic angle position sensor for
accurate angular measurement over a full turn of 360°. A sub range
can be programmed to achieve the best resolution for the
application. It is a system-on-chip, combining integrated Hall
elements, analog front end, digital signal processing and best in
class automotive protection features in a single device.
To measure the angle, only a simple two-pole magnet, rotating over
the center of the chip, is required. The magnet may be placed above
or below the IC.
The absolute angle measurement provides instant indication of the
magnet’s angular position with a resolution of 0.022° = 16384
positions per revolution. According to this resolution the adjustment
of the application specific mechanical positions are possible. The
angular output data is available over a 12 bit PWM output.
The AS5261 operates at a supply voltage of 5V and the supply and
output pins are protected against overvoltage up to +20V. In addition
the supply pins are protected against reverse polarity up to –20V.

6 Absolute Maximum Ratings
Stresses beyond those listed in Table 2 may cause permanent damage to the device. These are stress ratings only, and functional operation of
the device at these or any other conditions beyond those indicated in Electrical Characteristics on page 6 is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
