“I am supplying it with 5V (same line that’s supplying power to the sensors) to +Vsupply and grounding the -Vsupply….Wired to -Vs (ground) should be the two black leads and a jumper to the -V pin of the instrumentation amp….don’t worry about the REF pin.”
Really can I use the instrumentatio amplifier without use a supply negative. I have tried to use it with the pin V- connect to ground and it doesn’t work.
Might somebody explain how I can use it?
No public wish lists :(
