I have an application where I need 16 ADC channels and I am using the ATMega16 which has 8-channels
What is the best way to double the amount of channels? By best I mean part cost/availability/simplicity
I need to stick with DIP parts.
Should I use 8 2-ch analog MUXs?
I was looking at this 2ch MUX:
My only concern would be I am now multiplexing the analog signal twice (once external of the AVR and once internally) and that the loss may be considerable?
The analog values I will be reading are DC (i.e. I'm not measuring any AC-like waveforms... just the result of a voltage divider)
