Greetings from the amateur experimental avionics hackers and users community. I'm looking for the simplest DAC device that can provide power and audio through a single USB cable to an Android or iOS tablet like this one, and provide a single analog mic/phone interface. A single-channel, non-switched interface would be fine. Stereo would be ok too. It could be powered by 5v or 12v DC.
Any ideas?
