Hi, Nic,

Do you need a specific type of output (headphone, line, speaker outputs)? Stereo or mono output?

The TLV320DAC3203 supports this kind of output when the headphone outputs are used in mono differential mode. If you are looking for a speaker output, I would recommend the TAS2505.

Best regards,

Hi Luis,

We are looking for a stereo output. Headphone or line output should be fine as we have class-D amp following with the DAC output.

Regards,

Nic

Hi, Nic,

In that case, I would recommend the PCM5121. This Audio DAC supports up to 2Vrms. If the analog gain is configured at -6dB, the line output would be fixed at 1Vrms (full-scale).

Please take a look at it and let me know if you have additional questions or comments.
