SHH,
You need to still connect A_VDD and LS_VDD. See the note in operating ratings section:
Typically we recommend coupling unused inputs to gnd using a capacitor, but because you will not be using the ADC or DAC and they will always remain in mute, I don't think this is crucial.
The LM49350 or LM49352 are also capable of this function, and the cost on those devices is a little lower. it could save a considerable amount.
best regards,
