The ADA4939-1differs from conventional op-amps in that they have two outputs whose voltages move in opposite directions and additional input, VOCM. Like op-amps, it relies on high open-loop gain and negative feedback to force these outputs to the desired voltages. The ADA4939-1 behaves much like standard voltage feedback op-amps and facilitates single-ended-to-differential conversions, common-mode level shifting, and amplifications of differential signals. Like op-amps, the ADA4939-1 has high input impedance and low output impedance. Because it uses voltage feedback, the ADA4939-1 manifests a nominally constant gain-bandwidth product. Two feedback loops are employed to control the differential and common-mode output voltages. The differential feedback, set with external resistors, controls only the differential output voltage. The common-mode feedback controls only the common-mode output voltage. This architecture makes it easy to set the output common-mode level to any arbitrary value within the specified limits. The output common-mode voltage is forced by the internal common-mode feedback loop to be equal to the voltage applied to the VOCM input. The internal common-mode feedback loop produces outputs that are highly balanced over a wide frequency range without requiring tightly matched external components. This results in differential outputs that are very close to the ideal of being identical in amplitude and are exactly 180° apart in phase.
