Resolution does not apply to multiplexers.
It is NOT an A to D converter !
It’s a ROTARY SWITCH ! (and an ANALOG one at that)
That means ANALOG IN , ANALOG OUT
Does a SWITCH have a resolution (4,8,16 etc)?
What is the definition of ‘resolution’ ?
The resolution of an A/D converter is defined as the smallest change in the value of an input signal that changes the value of the digital output by one count. For an ideal A/D converter, the transfer function is a staircase with a step width equal to the resolution."
Does an ANALOG MULTIPLEXOR have a DIGITAL OUTPUT ?
Think about that.
(FYI, that’s why you can’t find it because
there is no such spec for a MUX.
It has a propagation delay (15nS).
That answers your question. It doesn’t ‘read’
voltages, it passes them. Just think of it
as an invisible switch , either on or off, ( but in
this case , rotating)
You should change your post title to:
‘No Such Number’
