AS5145 360 degree position sensor calibration

I got some samples of the AS5145 Automotive Rotary Encoder IC, and I did a quick test  for positioning of the motor using its PWM output signal thru a low pass filter to get analog out signal.

The absolute angle measurement provides instant indication of the magnet's angular position with a resolution of 0.0879° = 4096 positions per revolution.

It also has SPI (serial interface) as well Quadrature A/B (10 or 12 bit) and Index output signal, that will test and present in future video.
