 The ADS-1X15 ADC, this is the 16-bit one, this is the 1115, we also have the 1015, which is a 12-bit. This will give you up to four channels of high quality, high resolution analog to digital conversion. Perfect for knobs and sliders and soft potentiometers or other analog sensor reading needs. I'm going to be reading those knobs and turning those values into the frequency here on a pair of sawtooth waveform oscillators. So here I wanted to tune a nice interval and I can really fine tune that thanks to that high resolution of those ADCs. The ADS-1X15 16-bit and 12-bit ADC breakouts with Stem-AQ-T.
