TAS5421-Q1: Connection od TAS5421-Q1 to PCM5120

Part Number: TAS5421-Q1

Dear all,

 

one of my AA is evaluating the TAS5421-Q1 with the TAS5421EVM. In the set up he is using the PCM5102EVM to generate the signal.

Is the following connection allowable ?

 

PCM5102EVM                                         ->           TAS5421EVM

----------------------------------------------

J1-signal  (RCA output OUT_R)            ->           J2-2 (INP)

J1-shield  (shiled of RCA)                      ->           J2-1 (INM)

GND of PCM5102EVM                     ->           J2-6  (GND)

regards,

Domenico

  • Domenico,

    This should be fine but I will let Tuan comment to confirm.

    Hi Domenico,

    Tuan is on vacation, so I will help you. 

    The connections described are correct for single ended input.  If you have noise issues, the shield of the input connection (IN-) could be connected to the GND.
