Dear Team:

 Recently our customer  got Dell RFQ about DAC+line out solution.

But Dell line out spec.(SNR, THD+N, DR.) is base on 1Vrms.

Could you provide the data to me?

    Hi Thomas,

    For the PCM510X series, which outputs 2.1 Vrms, you would need to create a voltage divider to get down to 1 Vrms, since the part does not have the option to switch outputs. However, if you use the PCM512X or PCM514X parts, these are software controlled and have the ability to change the output to 1 Vrms. The register is on Page 1 register 0x02.
