4.1.17 Volume Control: Left Channel (address 04h) & Right Channel (address 05h)

Default = 0 (No attenuation)

Function:

The volume control allows the user to alter the signal level in 1 dB increments from +12 to -96 dB, when

the INDVC bit is disabled. When INDVC is enabled, the volume control can be altered in 1 dB increments

from 0 to -96dB. Volume settings are decoded as shown above, using a 2’s complement code. The vol-

ume changes are implemented as dictated by the Soft and Zero Cross bits in the Analog I/O Control reg-

ister. All volume settings less than -96dB are equivalent to muting the channel.

4.1.18 Left/Right Analog Gain (address 06h)

Default = 0 (No gain)

Function:

The level of the left and right analog channels can be adjusted in 1dB increments as dictated by the Soft

Ramp and Zero Cross bits from 0 to +12dB when routed through the PGA via the AINMUX bits. Levels

are decoded as shown above. Levels above +12dB are interpreted as +12dB.
