Hallo, I must develop a system that should accept at the input the following voltage ranges:
0 5v 0 10v 0 15vI thought two chances:
1) Using a voltage divider where I could choose the couple of resistor using 2 multiplexer. I connect every resistor to input of a mux and I configure the two mux using a couple of jumpers. Then I connect to oupt of voltage divider a opamp voltage follower or similar.2) Using a programmable gain amplifier.
There are orther chances?
Any comments is very appreciated.
Many Thanks Marco
