AS5163
14 bit Programmable Magnetic Angle Position Encoder
1 General Description
The AS5163 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

Board description
The AS5163 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: 5V power supply, GND and the output connection (KDOWN is optional). Only pin
1, 3, 5, and 7 of JP1 are connected. Capacitor C1 and C2 (both 2.2uF) is buffering the LDO outputs VDD3 and VDD5; C3 (1uF) is
placed between VDD and GND.

over a 14 bit digital protocol, a 12 bit PWM signal or 12 bit
ratiometric analog output.
The AS5163 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.
