Hello.
I'm interested in how can resistance signals (like Pt100) be
multiplexed?
I mean how can I make a analog switch to switch 16 RTDs
to just one output? Three wire Pt100 connection.
For analog voltages and currents amalog multiplexers like
4051 can be used but how about resistance (around 100
Ohms)? (analog multiplexer chips have pretty big resistance)
