运算放大器（op amp）中的一个关键技术概念是轨到轨（rail-to-rail）能力，意指运放的输入或输出信号能够极其接近其供电电源的上下限。传统运放常受限于输出电压范围，不能触及电源边界，而轨到轨运放则能使其输入或输出电压几乎达到电源的极值，从而在某些应用中提供了更大的灵活性和适用性。为了更好地理解轨到轨...

Rail-to-rail op amps are the perfect fit for applications where the supply voltage range is low and the full dynamic range is necessary at the output
A constant-Gm topology has been used in the input stage in order to obtain high linearity and good frequency compensation. The circuit shows rail-to-rail input and output characteristics and good performance as well as a high efficiency factor when compared with the other adaptive biasing ...
The power supply units of PCs and other devices incorporate multiple DC power supplies. A power supply line provided by a power supply unit is referred to as a power rail. The entire range from the maximum voltage of a power line (VCC) to its

Maxim's operational amplifiers' (op amps) use of rail to rail has nothing to do with railroads. Nonetheless, railroads make an excellent mental image to describe the phenomenon. Just as a train's rails place limits on the lateral movement of a train, op-amp power rails place limits...
