THEORY OF OPERATION
The ADA4932-x differs from conventional op amps in that it
has two outputs whose voltages move in opposite directions and
an additional input, VOCM. Like an op amp, it relies on high open-
loop gain and negative feedback to force these outputs to the
desired voltages. The ADA4932-x behaves much like a standard
voltage feedback op amp and facilitates single-ended-to-differential
conversions, common-mode level shifting, and amplifications of
differential signals. Like an op amp, the ADA4932-x has high input
impedance and low output impedance. Because it uses voltage
feedback, the ADA4932-x 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.
