Abstract :
This paper present a rail-to-rail single ended amplifier designed for driver applications requiring full range input and output swing with minimum distortion and noise. The amplifier drives an AC-coupled 270Ω/100pF load to within 0.1 V of either rail for operation between 2.1 V and 5.5 V with less than 0.02% THD in the audio band. This was achieved with a high gain amplifier (126 db) and a quiescent current of 330 μA. Operating at 3.3 V, it drives an AC-coupled 30Ω/100pF load 2Vpp with 0.016% THD
