8.3.3 Single-Supply Operation
The THS3125 and THS3122 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 in Figure 39 show inverting and noninverting amplifiers configured
for single-supply operation.
