*1. Current dissipation that is a sum of VCC1 and VCC2 at no load.

*2. Input AMP is a BUFFER AMP.

*3. Voltage difference between both ends of load (8Ω). Output saturated.

*4. Voltage difference between both ends of load (12Ω). Output saturated.

*5. The source of input OP-AMP is a constant current. (See the specified block diagram.)

As the 11kΩ resistance to the next stage is a load, pay due attention when setting the input OP-AMP gain.

*6. Output ON with MUTE: [H] and OFF with MUTE: [L] (HI impedance).

*7. Design guarantee value
