Data Sheet  
ADAU1463/ADAU1467  
The digital (DVDD) supply pins each have up to three local  
bypass capacitors, as follows:  
EXAMPLE PCB LAYOUT  
Several external components, such as capacitors, resistors, and  
a transistor, are required for proper operation of the device.  
An example of the connection and layout of these components  
is shown in Figure 90. Thick black lines represent traces, gray  
rectangles represent components, and white circles with a thick  
black ring represent thermal via connections to power or ground  
planes. If a 1.2 V supply is available in the system, the transistor  
circuit (including the associated 1 kΩ resistor) can be removed,  
and 1.2 V can be connected directly to the DVDD power net,  
with the VDRIVE pin left floating.  
•
The 100 nF bypass capacitor acts as a return path for high  
frequency currents from the DSP and other digital circuitry.  
The 1 µF bypass capacitor is required to provide a local  
current supply for sudden spikes in current that occur at  
the beginning of each audio frame when the DSP core  
switches from idle mode to operating mode.  
•
Of these three bypass capacitors, the most important is the 100 nF  
bypass capacitor, which is required for proper power supply  
bypassing. The 10 nF and 1 µF capacitors can optionally be used  
to improve the EMI/EMC performance of the system.  
The analog (AVDD), PLL (PVDD), and interface (IOVDD)  
supply pins each have local 100 nF bypass capacitors to provide  
high frequency return currents with a short path to ground.
