MKR GSM 1400 ADC question

Hello.

In the technical specifications of MKR GSM 1400 for ADC mentioned (ADC 8/10/12 bit).

What does it mean?

Is it possible to change ADC bits?

I also need information about ADC max speed (samples per second). How do I get this information.

Thanks in advance.

analogReadResolution(bits) function can be used to change the resolution of analogRead().

Thank you. Very Helpful!
