Are DVDD and AVDD of TAS5710 shorted internally?
Thanks in advance.

Hi, Toshi,
First of all, I would like to mention that this device is quite old, I would recommend one of our newer closed-loop Amplifiers, like the TAS5754/56, or TAS5760xx if you don't need high processing features. About your question, AVDD and DVDD are used to feed internal analog and digital circuitry of the amplifier, they are not shorted internally so you need to connect 3.3V supply to each one.

Hi, Toshi-san,
Thanks for the feedback. About your question, AVSS and DVSS corresponds to the internal analog and digital grounds, so they are not shorted internally. DVSS can be connected to the system GND directly and AVDD can be connected in a single point to ground as you can see in the Evaluation module. AVDD and DVDD can be connected to the same power supply (+3.3V).
