The following typical application examples on ISD1900 series are for references only. They make no
representation or warranty that such applications shall be suitable for the use specified. It’s customer’s
obligation to verify the design in its own system for the functionalities, voice quality, current consumption,
and etc.
In addition, the below notes apply to the following application examples:
•
It is important to have a separate path for each ground and power back to the related terminals to minimize
the noise. Besides, the power supplies should be decoupled as close to the device as possible.
Also, it is crucial to follow good audio design practices in layout and power supply decoupling. See
recommendations in Application Notes from our websites.
