CHANNEL B VOLUME CONTROL - ADDRESS 04H

6.4.1

Mute (Bit 7)

Function:

The Digital-to-Analog converter output will mute when enabled. The common mode voltage on the

output will be retained. The muting function is effected, similiar to attenuation changes, by the Soft

and Zero Cross bits in the Volume and Mixing Control register. The MUTEC pin for that channel will

go active during the mute period if the Mute function is enabled. Both the AMUTEC and BMUTEC

will go active if either MUTE register is enabled and the MUTEC A = B bit (register 5) is enabled.

6.4.2

Volume Control (Bits 6:0)

Function:

The digital volume control allows the user to attenuate the signal in 1 dB increments from 0 to -127 dB.

Volume settings are decoded as shown in Table 14. The volume changes are implemented as dictated

by the Soft and Zero Cross bits in the Volume and Mixing Control register (see section 6.2.2).

6.5

Mode Control 2 - Address 05h

6.5.1

Invert Signal Polarity (Bits 7:6)

Function:

When set to 1, this bit inverts the signal polarity for the appropriate channel. This is useful if a board

layout error has occurred, or an other situations where a 180 degree phase shift is desirable. Default

is 0.
