Single-Supply Op Amp Forms Noninverting Level Shifter

Abstract: Single-supply circuitry saves space and cost, but audio and video are usually referenced to ground, which requires two op amps and a negative rail. This circuit, however, uses only one op amp (MAX4380) to level-shift a ground-referenced signal while operating on a single supply voltage.
