Notes:

These components may be needed in order to optimize for the best voice quality and system performance,

which is also dependent upon the layout of the PCB. Pending upon system requirement, Cx can be 10 μF,

4.7 μF or other values. For R7, 1kΩ gives satisfactory result fro most cases.

** For Sampling Freq at 8 kHz, R4 = 80 KΩ

*** It is important to have a separate path for each ground and power back to related terminal to minimize the

noise. Also, the power supplies should be decoupled as close to the device as possible.

Good Audio Design Practices

Winbond’s ChipCorder are very high-quality single-chip voice recording and playback devices. To

ensure the highest quality voice reproduction, it is important that good audio design practices on

layout and power supply decoupling are followed. See Application Information links below for details.
