7.3 Pulse Width Modulation (PWM) Output

The AS5263 provides a pulse width modulated output (PWM), whose duty cycle is proportional to the measured angle. This output format is

selectable over the OTP memory. If output pins OUT_T, OUT_B are configured as open drain configuration, then an external load resistor (pull

up) is required. The PWM frequency is internally trimmed to an accuracy of ±10% over full temperature range. This tolerance can be cancelled

by measuring the ratio between the on and off state. In addition, the programmed clamping levels CLL and CLH will also adjust the PWM signal

characteristic.
