Hello,
I'm trying to use the TFA for an audio application and I would like to be sure that I understood correctly the product data sheet. It seems to me that a digital voltage supply between 1.65V and 1.95V should be externally provided. Is my understanding correct or is the 1.8v (STABA) output usable for this purpose?
Many thanks,
Serge

Hello Serge,
The 1.8V for VDDD needs to be supplied externally. The STABA (1.8V) cannot be used to supply VDDD.
Best regards,
Tomas
