单电源运算放大器窗体同相的电平转换器

摘要：单电源供电电路，节省空间和成本，但音频和视频通常引用到地面，这需要两个运算放大器和一个负轨。然而，该电路只使用一个运算放大器（ MAX4380 ）级转向以地为参考的信号，而单电源电压工作。

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
