Hi Team,

This is for Hifi application on motherboard.

Did we have DAC to replace ES9018K2M?

The output stage is LME49720 + OPA1622.

Thanks,

Hi Luis,

What is the adavantage we can beat ES9018?

Did we have plan for this spec device? why do not we propose PCM1795/6?

Thanks,

Hi, Scott,

Basically, the PCM1792A has the best DNR of the PCM devices. It can reach 129dB Stereo or 132dB Mono. It would be a better DNR than the ES9018. The rest of functions are similar.

Hi Luis,

Could you let me know the ES9018 specific DNR data? I saw on the web, the stereo DNR is 135dB.

Thanks,

Scott

Hi, Scott,

The document that you shared mentions that it is able to reach 135dB in mono applications. The PCM1792A is one of our DAC with better DNR performance, but it is under this value. The rest of features are similar in both devices.
