AUXL pin on TPS65930 audio?

Other Parts Discussed in Thread: TPS65930, DM3730, TPS65950, TPS65951

Hi,

We are currently working on a custom board using a TPS65930 together with a DM3730 and we would need some precision on the auxiliary audio input.

In the chip reference manual in Figure 13-4 an AUXL pin is mentioned as possible input for the Ampli_L. There are also some other references to AUXL throughout the reference manual (e.g. Table 13-10. ANAMICL Register --> AUXL_EN) but in the chip Data Manual there is no mention at all of an AUXL pin.

I assume that this is an error in the reference manual and that this chip does not have an AUXL path (mono input only). Could you confirm ?

For a stereo auxiliary input another codec (e.g. TPS65950) should be chosen or the configuration recommended in this thread should be implemented right ?

Thanks in advance for your tips and hints,

    Romain
