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.

The below example illustrates a typical applications of ISD1600B device.
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 μ F,
4.7 μ F or other values. For R7, 1k Ω gives satisfactory result fro most cases.
For Sampling Freq at 8 kHz, R4 = 80 K Ω
noise. Also, the power supplies should be decoupled as close to the device as possible.
