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
