General Description
The AS5263 is a redundant, 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
signal or 12 bit ratiometric analog output.
The AS5263 operates at a supply voltage of 5 V and the
supply and output pins are protected against overvoltage
up to +27 V. In addition the supply pins are protected
against reverse polarity up to – 18 V.

The AS5263 Demoboard
The AS5263 demoboard is a complete rotary encoder system with built-in microcontroller and graphical LCD display.
The board is externally supplied with a 9V battery or by the USB connection (standalone operation only).
