Split-Supply Operation (±1.35 V to ±6.3 V)

See the OPA2863DGK Evaluation Module user guide for more information on how the OPAx863 devices can be configured to allow for split-supply operation to facilitate testing with common lab equipment. This configuration eases lab testing because the mid-point between the power rails is ground, and most signal generators, network analyzers, oscilloscopes, spectrum analyzers, and other lab equipment reference the inputs and outputs to ground. Figure 9-1 depicts the OPAx863 devices configured as a noninverting amplifier and Figure 9-2 illustrates the OPAx863 devices configured as an inverting amplifier. For split-supply operation referenced to ground, the power supplies VS+ and VS- are symmetrical around ground and VREF is at GND. Split-supply operation is preferred in systems where the signals swing around ground because of the ease-of-use; however, the system requires two supply rails.
