TYPICAL APPLICATION CIRCUITS
The following typical applications examples on ISD1700 Series are for references only. They make no
representation or warranty that such applications shall be suitable for the use specified. Each design
has to be optimized in its own system for the best performance on voice quality, current consumption,
functionalities and etc.
The below notes apply to the following applications examples:
*
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 requirements, they can be 10
μF, 4.7 μF or other values.
Please refer to the applications notes or consult Nuvoton for layout advice.
** It is important to have a separate path for each ground and power back to the related terminals to minimize
the noise. Also, the power supplies should be decoupled as close to the device as possible
.
Example #1: Recording using microphone input via push-button controls
