Ok, I got it. I consulted with our supplier, then I got the reply that the DAC type of this module is not same with the type you mentioned. They called audio decoding DAC of this module. As for the specific internal structure, taking into account the market competition, they cant provide, hope for your understanding.

Hope these are useful to you. Wendy.Hu

2016-12-14 21:45:25 I make project and I use DFPlayer. I need information about type of DAC in DFPLayer (Binary Weighted Resistor, R-2R ladder etc.). Reason why I need have this info is to describe how this kind of DAC is working, and how it converts signals.

I've read documentation of DFPlayer MINI and internet, but I found nothing about what I need.

Thanks

Sorry, I have no idea about the type of DAC. Would you mind tell me something about the DAC type? Maybe this would let me help you better.
