8.2. Application Circuit - (Speaker/Microphone Shared)

PCB Layout Guidelines:

2. VSS and AVSS must be connected to power input port (GND) directly and independently, meaning not branch from one or another.

3. C2 is suggested 0.1uF, the IC power is more stable if increase C2.

And C2 should be as closed as possible in between VDD/AVDD
