16 / 24 page ![]() ISD1700 SERIES - 16 - 10 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 Winbond 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 .
