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. am lc s on A te G nt st il 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 2 The AS5263 Adapter board 2.1 Board description The AS5263 adapter board is a simple circuit allowing test and evaluation the rotary encoder quickly without building a test fixture or PCB. The PCB requires only a 3-wire connection per die: 5V power supply, GND and the output connection (KDOWN is optional) Capacitor C1, C2, C4 and C5 (all 2.2uF) are buffering the LDO outputs VDD3 and VDD5; C3 and C6 (both 1uF) are placed between VDD and GND. 4 x 2.6mm mounting holes JP1 connector (GND, power supply, output/interface) Figure 1: AS5263 Adapterboard Te ch ni ca AS5263 sensor Revision 1.0, June 2010 Page 1 of 6 www.austriamicrosystems.com/AS5263 AS5263 Programmable Magnetic Rotary Sensor Adapterboard Operation Manual 2.2 Mounting the AS5263 adapter board Bearing M2~M2.5 Screw + nut Casing Rotating shaft and magnet holder Spacer Not ferromagnetic (plastic, brass, copper, stainless steel, aluminum…) Te ch ni ca am lc s on A te G nt st il lv al id AS5263-AB PCB Figure 2: AS5263 adapter board mounting and dimension A typical diametric magnet (for instance 6x2.5mm) must be placed over on under the AS5263 encoder, and should be centered on the middle of the package with a tolerance of 0.5mm. The airgap between the magnet and the encoder casing should be maintained in the range 0.5mm~2mm. The magnet holder must not be ferromagnetic. Materials as brass, copper, aluminum, stainless steel are the best choices to make this part.

Use the Top Die by connecting in the same way. Figure 4: Operation cases with the adapter board The OUT pin (JP1 – 5) is used as output as well as programming interface. The AS5263 provides a pulse width modulated output (PWM) and an analog output mode. All modes are programmable in terms of output-voltage and corresponding angle. The Kick down (KDOWN) is an optional connection, used for instance in gas pedal applications. For further information, please refer to datasheet. 5 Programming the AS5263 ca For programming the AS5263 only 3 connections (VCC, GND and OUT) are necessary; please refer to Figure 4. It is recommended using the AS5000-Programmer and a connectionboard AS5x63-CB, shown in Figure 5, for fusing the device.
