Default LM4651/ LM4652 power supply

I hoping to build in the near future the LM4651/ LM4652 class D amp from national and i'm going to follow the pcb layouts and compenets that national has listed exactly since this is my first time building a class d amp, but one thing i haven't found on the datasheet which i must be skipping over is the recommended power supply. I know that 22v is required but how many amps, etc?? and also can a switching power supply be used( since this amp isn't of the highest sonic quality) ?
