9 Pulse Width Modulation (PWM) Output
The AS5045 provides a pulse width modulated output (PWM), whose duty cycle is proportional to the measured
angle:
( ) Position = ton ⋅ 4097 −1
ton + toff
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.
