8.4 Device Functional Modes

The Automotive grade of the OPAx607-Q1 family has only one functional modes: normal operating mode. The

PD mode exists only in some of the packages made available in the industrial grade of the OPAx607-Q1 family.

8.4.1 Normal Operating Mode

The OPAx607-Q1 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

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.
