2.2 Single-Supply Operation

To operate as a single supply, apply the positive supply voltage to VCC and the ground reference to VEE.

The input common mode voltage is at the node between R25 and R26. To apply a voltage at this node, add resistors R25 and R26 and adjust the values to obtain a midpoint or other voltages between the supplies. A high-frequency 0.1 ΩF decoupling capacitor connected to VCM can be included as C4 on the board.
