do not bother with output impedance, normally it is defined directly by the opamp, ideally it should be small ... the resistance of R10/R11 can help with capacitive loads, use anything between 50-100R

DAC AD1862: Almost THT, I2S input, NOS, R-2R
Hello friends, anyone can tell me the max sample rate ad1862 plays or admits??
i am asking because i try to play upsampled files to 768khz and play at low volume, but i ear crackles and distortion when i turn volume higher.
It is strange because i try the same jdlsoundsi2soverusb board with pcm1702 and 1704 and both play 768khz perfect with no cracks or distortion.

I've used both JLCPCB and LCSC for several years. Service and prices have been very good. LCSC's parts inventory is not huge so I still often also use Mouser and Digikey.

Parts selection on LCSC's website can be slow. Many manufacturers are unknown to me and datasheets are often only in Chinese. The cost savings are usually worth the extra effort.

Thanks.

Seems a big reseller, so I think that all the components are original. What do you think about it?

Not sure what you are asking. Nothing I have received from LCSC has been obviously fake or defective. They appear to be a large industrial supplier much like Mouser and Digikey.
