Hello experts,

I have question for Amplication rate of PCM1754.

I want to know Amplication rate of "Output Amp" in the figure below,

but Icould not find it on the datasheet.

Could you  tell me about it ?

Best reards.

    Hello, 

    As you mentioned the  internal amplification is not mentioned in data sheet . But we know  the combination  gain of  both internal DAC and Output amp shown in the diagram  is such that for a full scale input,   the IC is capable of delivering a voltage at each  output pin  that is about 80% of applied VCC, namely 4V for a 5V supply.

    is there any reason that you need  the internal gain of amplifier stage ?

    Regards,
