8.2.1 Single-Ended to Differential with 2.5-V Output Common-Mode Voltage
Most real-world signals are single ended. Often, fully differential amplifiers (FDAs) are used for single-ended-to-differential conversions but the low-impedance input of the FDA configuration can be a challenge for digital acquisition systems (DAQs). The high input impedance input of the OPA862, coupled with its ability to convert single-ended inputs to differential outputs, makes the device an excellent choice for DAQs.
