I need an ADC can take Negative voltage

Anonymous · ‎May 22, 2017

Hello there,

I have a project that required a bidirectional ADC which can take negative and positive voltages.

What is the best solution to do so using PSoC 5LP? I have MAXREFDES5#, and I am thinking about using it, but I know the design will be complex. If these is a suggestion or an example code that would help me to build my design faster I would be grateful.

Thanks!

You need a resistor network to shift the expected input voltage into the range (roughly) GND .. VDDA.

Look at this thread which I found by putting "negative voltage" into the search field at top of this page.
