TPA3128D2: TPA3128D2 mode selection

Part Number: TPA3128D2

Tool/software:

Hello,

We are planning a new design with multiple TPA3128 on a board with DSP and DAC's.

DSP needs boot time, after which the DAC's initialize, so I want to keep the output stages dead until

audio path is up and running.

Two questions regarding this implementation of the TPA3128D2;

Concerning the mode selection: Is the state of the selection pin (1) latched at power-up only,

or latched at the release of SDZ (2) or can it be changed on the fly?

Second question concerns the charging of the input caps: only at initial power-up or also

after SDZ release?

kind regards

Geert de Vries
