9 Pulse Width Modulation (PWM) Output
The AS5040 provides a pulse width modulated output (PWM), whose duty cycle is proportional to the measured
angle:
The PWM frequency is internally trimmed to an accuracy of ±5% (±10% over full temperature range). This tolerance
can be cancelled by measuring the complete duty cycle as shown above.
