Unless otherwise noted, the supply voltage is VPP=14.4V, RL = 4Ω. Measurement Bandwidth = 20kHz. See Application/Test Circuit. . Note 9: The TA2041A 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. Protection Circuits (Note 8) TA = 25°C. Unless otherwise noted, the supply voltage is VPP=14.4V. SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
