Note 2 :
This circuitry is intended for applications where the CS 43L21 connects directly to an unbalanced output of the device . For
internal routing applications please see the DAC Analog Output Characteristics section for loading limitations .

Note 1:
Series resistance in the path of the power supplies (typically
used for added filtering) must be avoided. Any voltage drop
on VA_HP will directly impact the negative charge pump
supply (VSS_HP) and result in clipping on the audio output .
