7.4.1 Split-Supply Operation (±1.5 V to ±6.3 V)

To facilitate testing with common lab equipment, the OPA862 can be configured to allow for split-supply operation. 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. For split-supply operation referenced to ground, the power supplies VS+ and VS– are symmetrical around ground and generally VREF is also set equal to ground. 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.
