SLES102B December 2003 – March 2015 PCM1798
The PCM1798 requires a 5-V nominal supply and a 3.3-V nominal supply. The 5-V supply is for the analog circuitry powered by pins VCC1, VCC2L, and VCC2R pins. The 3.3-V supply is for the digital circuitry powered by the Vdd pin. The decoupling capacitors for the power supplies should be placed close to the device terminals.
