8.4.1 Normal Operating Mode

The OPAx607 devices are operational when the power-supply voltage is between 2.2 V (±1.1 V) and 5.5 V (±2.75 V). Most newer systems use a single power supply to improve efficiency and simplify the power tree design. The OPAx607 devices can be used with a single-supply power (VS– connected to GND) with no change in performance from split supply, as long as the input and output pins are biased within the linear operating region of the device. The valid input and output voltage ranges are given in Section 7.5. The outputs nominally swing rail-to-rail with approximately 10-mV headroom required for linear operation. The inputs can typically swing up to the negative rail (typically ground) and to within 1.1 V from the positive supply. Figure 8-6 shows changing from a ±2.5-V split supply to a 5-V single-supply.
