*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 (12

Ω).

*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 11k

Ω 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.
