Figure 12: OTP Programming Hardware Connection of AS5043 (shown with AS5043 demoboard)
12.1 Zero Position Programming
The AS5043 allows easy assembly of the system, as the actual angle of the magnet does not need to be considered. By
OTP programming, any position can be assigned as the new permanent zero position with an accuracy of 0.35° (all
modes).
Using the same procedure, the AS5043 can be calibrated to assign a given output voltage to a given angle. With this
approach, all offset errors (DAC + OPAMP) are also compensated for the calibrated position.
Essentially, for a given mechanical position, the angular measurement system is electrically rotated (by changing the
Zero Position value in the OTP register), until the output matches the desired mechanical position.
The example in Figure 13 below shows a configuration for 5V supply voltage and 10%-90% output voltage range. It
adjusted by Zero Position Programming to provide an analog output voltage of 2.0 Volts at an angle of 180°. The slope of
the curve may be further adjusted by changing the gain of the OPAMP output stage and by selecting the desired angular
range (360°/180°/90°/45°).
