PCB layout notice:
1. Use two lines to connect PAD1 and PAD31. The VDD line connected to PAD31 should be wider
2. Use two VSS2 lines to connect PAD36 and PAD48 (for AU1564 and AU1564A, connect PAD
3. Use the VDD line connected to PAD1 as the down-bond substrate.
36 and PAD 46). The VSS2 line connected to PAD48 (for AU1564 and AU1564A, connect
PAD 46) should be wider than another one. Because PAD48(for AU1564 and AU1564A, PAD
46) must sink the higher current.
than another one. Because PAD31 must supply the higher current.
