Notes:
* These
capacitors may be needed in order to optimize for the best voice quality, which is also dependent
upon the layout of the PCB. Depending on system requirement, they can be 10

It is important to have a separate path for each ground and power back to the related terminal to minimize
the noise. Also, the power supplies should be decoupled as close to the device as possible.

To ensure the highest quality of voice reproduction, it is important to follow good audio design
practices in layout and power supply decoupling. See Application Information or links below for
details.
