*1: The total current dissipation for VCCP1, VCCP2, and VCCS with no load.
*2: The input amplifier is a buffer amplifier.
*3: The voltage difference between the two sides of the load (12Ω).
*4: When the MUTE pin is high, the output will be on, and when low, the output will be off (high-impedance state).
*5: The input operational amplifier source is constant current. Since the 11kΩ resistor between this and the next stage functions as the load, the input
operational amplifier gain must be set carefully.
*6: The braking operation is a short (to ground) braking operation. The sink side output is on at this time.
*7: Design guarantee.
