veqtor Posted September 12, 2012 Report Share Posted September 12, 2012 So, I was thinking about getting a Papilio one but I have some questions:Is it possible to realize an ADC using sigma delta?Something like this:http://www.hitequest.../adc_dsigma.jpgWhat is the stability of the DAC using sigma delta? Can I use it to control analogue synthesizers, that is, is it stable or jittery?In a modular, oscillators are controlled using "control-voltage" where 1volt = one octave so that's 0.083333... volts per semitone. That means a 0.001 jitter will be audible instability. So I will probably need an external dac or? I will need to amplify the output to cover something like a +/-5 volts range (10 octaves).I hate smd soldering, any other options for high-res dacs?
