power supply and grounding
The PCM1606 requires a 5-V supply. The 5-V supply is used to power the DAC analog output-filter circuitry, the
digital filter, and the serial interface circuitry.
Two capacitors are required for supply bypassing, as shown in Figure 29. These capacitors should be located
as close as possible to the PCM1606 package. The 10-
F capacitors should be tantalum or aluminum
electrolytic, while the 0.1-
F capacitors are ceramic (X7R type is recommended for surface-mount
applications).
