12.2.1 Angular Range Selector
The Angular Range selector allows a digital pre-selection of the angular range. The AS5043 can be configured for a full
scale angular range of 45°, 90°, 180° or 360°. In addition, the Output voltage versus angle response can be fine-tuned by
setting the gain of the OP-AMP with external resistors and the maximum output voltage can be set in the DAC.
The combination of these options allows to configure the operation range of the AS5043 for all angles up to 360° and
output voltages up to 5.5V.
The response curve for the analog output is linear for the selected range (45°/90°/180°/360°). In addition, the slope is
mirrored at 180° for 45°- and 90°- modes and has a step response at 270° for the 180°-mode. This allows the AS5043 to
be used in a variety of applications. In these three modes, the output remains at V out,max and V out,min to avoid a sudden
output change when the mechanical angle is rotated beyond the selected analog range. In 360°-mode, a jitter between
V out,max and V out,min at the 360° point is also prevented due to a hysteresis.
