I've been researching and learning about this for a few days.. but I still can't get a grasp of the options I have.
I can already sense that the most of the experts on this forum will be sick of hearing the 'teensy 4.0, no dac, panic' thread - yeah sorry in advance, I couldn't find a resolution
So right now :
- I make tiny synth like the photo above. Uneducated circuit design but they work. They work on teensy 3.2, with teensy audio library and dac output on pin 14.
- I've bought like 10 teensy 4.0 when it came out, not having read that it doesn't have a DAC like the stupid blob I am.
- I'm trying to avoid using the teensy audio adaptor to minimize the amount of space my projects take on a board. Especially when the audio adaptor stacks on top of the teensy!
- Back when I was using 3.2, line connection to pin 14 was just the right minimal set up I needed but... I gotta use my 4.0s somehow.
And I learned :
- I could use an external DAC chips. I found chips like MCP4822, MCP4922, MCP4728. they *look* like what I need but I can't seem to find anyone mentioning them with teensy to work with teensy audio library. And I can kind of see why - I thought I could connect them up somehow and just use the dac component in teensy audio library - but it looks like the dac component is specifically for the inbuilt dac (i.e. pin 14 on teensy 3.2).
- some other chips like PCM5102A or STGL5000. They look okay but they're REALLY small! I was imagining a chip size that I can use on prototyping board or breadboards. And also they're either all sold out or I can't get them from where I live (S Korea)
- PT8211 adaptor maybe? Except that my hands are noodles and I'm worried that I'll mess up the soldering of that tiny tiny chip... and also I will have no idea when I'll get international orders because of the pandemic... AND also because they stack, I'm trying to avoid.
- I'm really reluctant to use MQS... I do want better sounds..
My question is :
- I believe MCP4822 is what I'm looking for.. but I can't find any projects that use audio library and the chip to output audio! Have I missed something?
- Realistically, am I stuck in a needlessly strict specification? Maybe i'm being a tad stubborn and needy.
Thank you guys,
you guys are GREAT.
