Thanks for the reply ziko :) Yes I did some testing with a multimeter, and the samples seemed reasonably linear up to around +/- 4.5V, however I was only applying the voltage to channel #1 whilst monitoring all channels. I also found that as the applied voltage approached +/- 5.0V, that the linearit...

I’m monitoring the voltage output from various sensors, where the voltage occasionally exceeds the +/-2.5 Volts range specified in the ADC-16 User’s Guide. Now I found that when configured for 16 bit sampling, that as expected, the ADC-16 would max out at roughly +/-2.49 Volts. However I also found ...
