more analog inputs

I want to connect more than 6 analog inputs using a demultiplexer.
Is there any downgrade in 10bit resolution of each analog input? Will all the inputs remain 10bit or is there any speed downgrading?

Thanks in advance

There’s no downgrade or change whatsoever. You hook up for instance a CD4051 8 channel mux ic to one of your existing analog pins. The analog signal is just coming through the 4051 to an anlog pin.

You will ned 1 analog pin and 3 digital to control / read the 4051.
