Yeah, I'm thinking to use its ADC as a measure device with Eric Wallin's preamp 2 microphone preamp (green inputs). I don't know why there are capacitors in the picture because text says there are internal HiPassFilter that removes DC offset? So I don't have to put any caps to signal path?

Here is some schematics of that AK4584:

An externally hosted image should be here but it was not working when we last tested it.

DZF in Zero Input Detect Pin (output) so I think it can be used to turn amp off when there isn't anything in the ROUT & LOUT. It says in the page 8 of the datasheet that DAC analog output is 3 Vpp (@5V VREF). So if I use opamp, I don't need too much gain?

I did some more searching (a little too much, I think) and there was op amps (which sounded promising) like LM4562, OPA627, AD843.. And then I found discrete opamps / discrete output stages. And then.. I'm now considering Lampizator. :smash:

So hard to decide what to do.. :xeye:
