Note:
11. RC coupling at each input (parts shown dotted) might change depending on the PWM control scheme used in the application and the wiring impedance of the application’s
printed circuit board. The input signal section of the SPM 55 product integrates 10 kΩ (typ.) pull-down resistor. Therefore, when using an external filtering resistor, please pay
attention to the signal voltage drop at input terminal.
