It is true, it will limit measurements of many of the great DACs coming out now.Music1969, well, it looks unacceptable noisy yet -112db@2V.
I have no idea how it is possible to get such a noisy buffer(gain=0db!) with just Ok opamps(not to mention best-in-class opamps)..
sure, and AC coupling caps too but that doesn't affect the noise performance of the simulation.It might be useful to add a resistor on each input to ground to allow use with an AC-coupled source.
I am sure you are aware of it, but someone less experienced may forget it.sure, and AC coupling caps too but that doesn't affect the noise performance of the simulation.
We are keeping our Aliexpress storage for the last 20pcs Cosmos ADC, and preparing for the production new version Cosmos ADCiso(isolated USB version).Is the Cosmos ADC no longer in production or in a parts shortage situation? I tried to order one from HiFiGo, who said they had it in stock, but now they are saying that "the number of E1DA Cosmos ADC is limited" and will not be able to ship it. I see some on AliExpress but I'm not sure if those are for real or not.
no, the gain is too low for MC, but 60db of Cosmos APU is fine.if one or two low level impedances such as 100/150 and 470ohm.. input impedance adjustment, could become a phono prepre for somes mc cartridges (
26 db which can sometimes be a sufficient gain with certain mc cartridges)
?
