How to use:
1. When L and N are connected to AC220V, VCC, GND input DC5V?30V. Connect OUT and GND to an oscilloscope to get a sine wave.
2. Adjusting the potentiometer can change the amplitude of the output waveform (the middle value will not change during the adjustment process), and the waveform in the 0?VCC range.
3. If waveform distortion occurs in the process of increasing the amplitude, can be solved by appropriately increasing the working voltage VCC. If you want to move the middle value of the waveform to 0 o'clock, you can connect a capacitor of about 105pF in series with OUT to filter out the DC component in the waveform.
