I'm trying to choose a good op amp for a Class A small signal audio amplifier circuit.
I've done my research and understand the use pull up or pull down resistors externally to force Class A operation, and other specs influencing op amp choice generally.
What I can't find in my research is this - when choosing an op amp for use in a Class A design, is there an advantage to one type of internal op amp output stage type?
- rail-to-rail emitter follower
- totem pole (NPN-NPN)
- common collector (NPN-PNP)
