7.3.3 Single-Supply Operation
The THS309x have the capability to operate from a single-supply voltage ranging from 10 V to 30 V. When
operating from a single power supply, biasing the input and output at mid-supply allows for the maximum output
voltage swing. The circuits shown in Figure 62 show inverting and noninverting amplifiers configured for single-
supply operations.
