Abstract

A low-voltage rail-to-rail amplifier that has a NPN PNP switchable differential input stage allowing rail-to-rail input voltage swings is presented. The inputs can be overdriven without causing phase reversal in the output signal. The amplifier provides rail-to-rail output voltage swings which extend to within 50 mV of either rail. The output stage is current boosted to provide up to 50 mA of drive current.<>

四极低压轨对轨运算放大器

提出了一种具有NPN - PNP可切换差分输入级的低电压轨对轨放大器，允许轨对轨输入电压波动。输入可以被过度驱动而不引起输出信号的相位反转。放大器提供轨道到轨道的输出电压摆动，延伸到任何轨道的50毫伏以内。输出级是电流增强，以提供高达50毫安的驱动电流。
