Hello,

Does anyone know the order of magnitude of the analog input channels?
The data sheet is a bit confusing :confused:

thanks

Thanks Travis, I suppose it's the ON resistance of th input path, isn't it?

Sorry, may be I wasn't clear enough.

I mean what is the "input bias current" for an ADC channel, because we see a consumption of about 15mA,
and that value doesn't correspond with any parameters of the data sheet.

What's your sample time? I.e. how long does your measurement take and how much time is between measurements?

I think we found the problem, it was a faulty zener that leakaged the current before the ACD channel.
Thanks to all.
