Analog Mode Tab
Five bits of the OTP are used to configure the AS5046 analog output modes. (For more details please refer to the data
sheet)
Analog Output Range:
The Angular Range selector allows a digital pre-selection of the angular range. The AS5046 can be configured for
a full scale angular range of 45°, 90°, 180° or 360°.
