*1 : These parameters are not tested.

*2 : The gain from input to output when only the VIN* pins are used.

*3 : The MUTE pin voltage when the output changes between the on and off states. When the MUTE pin is high, all the BTL amplifiers will be on, and the when

MUTE is low, all the BTL amplifiers will be off.

*4 : The 5V regulator voltage when the RESET pin goes from high to low.

*5 : The 5V regulator voltage difference between the RESET pin going from high to low the RESET pin going from low to high. That is, the hysteresis.
