PP, May 2008, Rev 3.1

In Rx Voice Mode (AINLMODE=01, AINRMODE=01), adjustable gain control is available for the

RXVOICE output by use of the LR4BVOL[2:0] and LL4BVOL[2:0] register fields on the left channel

and by RL4BVOL[2:0] and RR4BVOL[2:0] on the right channel. Both Volume fields for the desired

channel(s) must be set to the same value for true Differential input characteristics. This configuration

is illustrated in Figure 25. The applicable register settings are shown in Table 10.
