Note: The components in the above application diagram are described:
Ci: Straight capacitance, in 0.1µF or less, further eliminates clatter-pitting and noise coupled in from the input.
Cs: Power decoupling capacitor, use a sufficiently low ESR capacitor (less than 1µF), when VDD=5V, it is recommended to add another low ESR capacitor (not less than 10µF) to better filter out low frequency noise. The closer the decoupling capacitor is to the VDD pin, the better. Keep it within 1.5mm.
INBYP: The INBYP port outputs VDD/2 voltage and is grounded through a capacitor C B (1µF) for stability. If the PCB design needs to consider the compatibility with other products of the same type, the resistance R0 position can be reserved, and the 0 ohm resistance can be used when producing the patch. If you do not need to consider the compatibility with other products of the same type, you can remove the resistance R0 and directly short-circuit it.
