7.2 Analog Output
The reference voltage for the Digital-to-Analog converter (DAC) is taken internally from VDD. In this mode, the output voltage is ratiometric to the
supply voltage.
7.2.1 Programming Parameters
The Analog output voltage modes are programmable by OTP. Depending on the application, the analog output can be adjusted. The user can
program the following application specific parameters:
The above listed parameters are input parameters. Over the provided programming software and programmer, these parameters are converted
and finally written into the AS5163 128-bit OTP memory.
7.2.2 Application Specific Angular Range Programming
The application range can be selected by programming T1 with a related T1Y and T2 with a related T2Y into the AS5163. The internal gain factor
is calculated automatically. The clamping levels CLL and CLH can be programmed independent from the T1 and T2 position and both levels can
be separately adjusted.

mechanical range. A sub range of the internal Cordic output range is used and mapped to the needed output characteristic. The analog output
signal has 12 bit, hence the level T1Y and T2Y can be adjusted with this resolution. As a result of this level and the calculated slope the clamping
region low is defined. The break point BP defines the transition between CLL and CLH. In this example, the BP is set to 0 degree. The BP is also
the end point of the clamping level high CLH. This range is defined by the level CLH and the calculated slope. Both clamping levels can be set
independently form each other. The minimum application range is 10 degrees.
