Register 16425 (0x4029), Playback Power Management
This register controls the unity current supplied to each functional
block described. Within the functional blocks, the current can
be multiplied. Normal operation has a base current of 2.5 μA,
enhanced performance has a base current of 3 μA, power saving
has a base current of 2 μA, and extreme power saving has a base
current of 1.5 μA. Enhanced performance mode offers the best
audio quality but also uses the most current.
Bit [7:6], Speaker Amplifier Bias Control
These bits control the amount of unity bias current allotted to
the speaker amplifier.
Bits[5:4], DAC Bias Control
These bits control the amount of unity bias current allotted to
the DAC.
Bits[3:2], Back-End Bias Control
These bits control the amount of unity bias current allotted to
the playback mixers and amplifiers.
Bit 1, Back-End Right Enable
This bit enables the playback mixers and amplifiers.
Bit 0, Back-End Left Enable
This bit enables the playback mixers and amplifiers.
