Hi Hao,

No there is no app note.

Class A and Class B are amplifier classes.

Class B will result in lower power usage of the part.

Class A will have better distortion, and transformerless applications must use class A.

Hi Hao,

Yes, class A can be used for transformer applications. Power consumption will go up tho. I do not have an indication of how much power will go up at this time.
