AS5043
Data Sheet – Mode Input Pin
9 Mode Input Pin
The absolute angular position is sampled at a rate of 10.4kHz (t=96μs) in fast mode and at a rate of 2.6kHz (t=384μs) in
slow mode.
These modes are selected by pin MODE (#2) during the power up of the AS5043. This pin activates or deactivates an
internal filter, which is used to reduce the digital jitter and consequently the analog output noise.
Activating the filter by pulling Mode = LOW reduces the transition noise to <0.03° rms. At the same time, the sampling
rate is reduced to 2.6kHz and the signal propagation delay is increased to 384μs. This mode is recommended for high
precision, low speed and ≤ 360° applications.
Deactivating the filter by setting Mode = HIGH increases the sampling rate to 10.4kHz and reduces the signal propagation
delay to 96μs. The transition noise will increase to <0.06° rms. This mode is recommended for higher speed and full scale
= 360° applications.
Switching the MODE pin affects the following parameters:
