As shown in the picture, the audio chip I use is TLV320AIC3101IRHBR, and the datasheet is connected to a capacitor. How do I determine which magnetic bead and capacitor to use?

Magnetic beads block high-frequency current, capacitor short-circuit high-frequency voltage

You can know the amount of welding.

In the above figure, FB16 and FB8 are inductors connected in series to VCC3_3. FB16 is connected to two capacitors, and FB8 is connected to ground. There is nothing special about it. Generally speaking, there are two benefits of series inductance: 1. Cut off a specific power supply when it is convenient for debugging to verify certain performance indicators; 2. Filter to prevent high-frequency current. The parallel capacitor is nothing more than a decoupling function.
