Note 9: The TAA4100A heat sinking in AM Mode must be increased (as compared to Class T mode) to sustain the
typical output numbers. This is due to the lower efficiency of Class B output stage operation. Please note that the
AM Mode operating supply range, due to this increased power dissipation, is 10V-16V.
