A three wire source has differential output but uni-polar(only one signal wire varies wrt AGND). Ground wire is AGND, the the other two is signal SG and the reference SGref. I'm trying to amplify the transducer signal with a gain of ten by using a non-inverting amplifier.
Since the transducer is not single ended output I'm bit confused. Which topology is correct?
At page 41 here shows the differential wiring of channels and at page 37 it says:
The transducer outputs are designed to work with a differential input to the DAQ system for best performance. Transducer outputs are ground-referenced differential signals. The output impedance of each DAQ signal is 100Ω
(I checked the output and only SG moves wrt to AGND but not SEGref so I think it is unipolar even though differential ended)
