This circuitry is intended for applications where the
CS42L51 connects directly to an unbalanced output of the
device. For internal routing applications please see the

* *Use low ESR ceramic capacitors.
See Note 4
Note 4
:
Series resistance in the path of the power supplies 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.

See Note 5
Note 5 :
Larger capacitors, such as 1.5 μF, improves the charge
pump performance (and subsequent THD+N) at the full
scale output power achieved with gain (G) settings
greater than default.
