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 over a 14 bit digital

2 The AS5163 Demoboard

The AS5163 demoboard is a complete rotary encoder system with built-in microcontroller and graphical LCD display.
The board is externally supplied with a 9V battery for standalone operation.

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.
