Why does this type of accelerometer need split supply. In the data-sheet this is described as a excitation voltage. But the diagram they provide does not show any +/- rails or any excitation Wheatstone bridge ect.
I cannot find any illustration about this type of accelerometer. And their data-sheet is not clear as well.
How can we illustrate this type of accelerometer along with their +- power/excitation connections? What is being excited here? Are +- power inputs supply anyother unit besides the opamp rails?
