10.1 Earphone Interface Electrostatic Protection Solution
Solution Advantages: Placing ESD diodes on the left and right audio channels as well as the MIC signal lines provides protection for downstream chips. Depending on the situation, additional ferrite beads can be added to filter out noise. You can choose ESD diodes rated at 3.3V or 5V, ensuring signal integrity while passing ESD tests. This solution meets the following standards:
IEC 61000-4-2, with contact discharge up to 30kV and air discharge up to 30kV,
ISO 10605-2 Level 4.
