A better ADC: the ADC08200

A project log for 20Msps+ ADC RaspberryPi HAT

Always wanted to have Msps ADCs on a Raspberry ... Let's dig into it.

Again, been playing with Jupyter to test this news ADC: https://github.com/kelu124/bomanz/blob/master/ADC08200/20170430-ADC08200-FirstAcqs.ipynb

This yielded interesting results: here's for example a small emulation of a ultrasound signal at 2MHz: we do see something

Not bad! The oscilloscope gives the same results:

You will note that I have put an offset of around 650mV to the signal so that it fits within the range of the ADC. The FFT domain does not look bad neither:

So I'm quite happy with it! Again see the full notebook at https://github.com/kelu124/bomanz/blob/master/ADC08200/20170430-ADC08200-FirstAcqs.ipynb
