Rail Splitter, from Abraham Lincoln to Virtual Ground

资料介绍
摘要:铁路分裂是一个人造的虚拟接地作为参考电压。它是用来设置信号匹配运算放大器的“甜蜜点” 。运算放大器具有最线性,无失真的品质,甜蜜点。通常情况下,甜蜜点附近发生单电源轨和地面之间的中心。在信号的情况下,虚拟的地面控制复或开关信号时,通道的DC错误。

Rail Splitter, from Abraham Lincoln to Virtual Ground
By: Bill Laumeister

Abstract: Rail splitting is creating an artificial virtual ground as a reference voltage. It is used to set the signal
to match the op amp's "sweet spot." An op amp has the most linear- and distortion-free qualities at that sweet
spot. Typically, the sweet spot occurs near the center between the single power rail and ground. In the case……
