8.4.3.2 Output Set to Mid-Supply Voltage

By connecting one reference pin to VS and the other to the GND pin, Figure 8-5 shows that the output is set at half of the supply voltage when there is no differential input. This method creates a ratiometric offset to the supply voltage, where the output voltage remains at VS / 2 for 0 V applied to the inputs.
