Part Number: PCM1803A

Hello,

It is not clear which of REF1/2 is for L/R channel. Is REF1 for L channel as the diagram in top page of datasheet implies?

Thanks!

Regards,

Oguri

    From the Datasheet I could  see the following. While i am not 100% sure I make the below inferences.

    1.Vref1=0.5*Vcc or a center voltage of 2.5v

    2. Vref2 to GND voltage  was a voltage equal to the analog full scale voltage. As per datasheet 0.6*Vcc=3vpp is full scale range. The Vref2 should then be a DC voltage of 3v
