  1. Hey guys Just wondering whether these 12bit ADCs from TI are a straight swap out with the Retrocade 8bit ones: http://www.ti.com/lit/ds/symlink/adc128s102.pdf The 8bit ones are: http://www.ti.com/lit/ds/symlink/adc088s102.pdf It's not a big deal at the moment for prototyping and the grove analogue block was written for 12 bit ADCs by the look of it (not sure why?), so I probably won't desolder the ones I have. However I thought when I get my own custom megawing built I could just swap these 12 bit ADCs straight in. Also, sometimes I get spurious 'crosstalk' between my ADC inputs but I'm not using all of them and the unused ones are currently floating unfortunately. Do you think the interference is likely the floating inputs or a dry solder joint (the situation tends to improve when I press on ADC0). I'm only using c0, c2, c4 and c6 of ADC0. Any thoughts? Cheers! Matt
