Splitting the Supply

By connecting one reference pin to V+ and the other to the ground pin, the output is set at half of the supply

when there is no differential input, as shown in Figure 37. This method creates a midscale offset that is

ratiometric to the supply voltage; thus, if the supply increases or decreases, the output remains at half the

supply.
