4 | +### Design Notes PAM8403 |
|
5 | +* Two ends of C32 and C34 must connect over PVDD and PGND. |
|
6 | +* To prevent to noises to speaker:<br /> |
|
7 | + * Pin 3 and Pin 14 should go under the IC to the speaker |
|
8 | + * Pin 4 and Pin 13 should NOT go under the IC to the speaker |
|
9 | + * Pin 2 and Pin 15 should NOT go under the IC to the speaker |
|
10 | +* Pin 6 VDD should separated with PVDD, pass C36 cap and after relatively long distance, and finally connect to VCC pin from two trace lines (to make this distance). |
|
11 | +* Not recommended to use single layer board. |
|
12 | +* circuits in the dot line box is optional. |
