TAS3204 single ended input, converter registers

Other Parts Discussed in Thread: TAS3204

Hello:  I am passing along these inquiries from my customer: 

>>>> For single ended (RCA) inputs, I want to make sure that there are no issues with using the TAS3204 ADC in single ended mode.  The EVM uses an extra inverting stage to convert all RCA single ended inputs to differential inputs for the ADC's -- why is that?   

The other issue is the TAS3204 registers that control some internal parameters for the ADC's and DAC's (0x13 ~ 0x1D).  Without getting into the specifics for each register, I would like to know in general if there is ever any reason to change these registers from the default values.    >>>>

  • George,

    There're two two ADC input mode: single ended and differential, I am not a HW person, but I have the impression that differential always has advantage from noise perspective, but I am not sure about this.  I've never heard of issues regarding th single ended mode, I assume it's fine.

    Regarding the registeres controling ADCs and DACs, I think the default value are the recommended settings, you would only need to set to other values when you have specific needs such as a different current settings etc.

    If you need more detailed answers, then I'll need to find someone familiar with the HW to ask.

    regards,
