Note *1 : Current dissipation that is a sum of VCC1 and VCC2 and S-VCC at no load.

*2 : Design guarantee value

*3 : Input AMP is a BUFFER AMP.

*4 : Voltage difference between both ends of load (8

Ω). Output saturated.

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

*6 : The source of input OP-AMP is a constant current. As the 11k

Ω resistance to the next stage is a load, pay due attention when setting the input

OP-AMP gain.

*7 : Short (GND) brake used. SINK side output ON.

*8 : 3.3VREG incorporates a drooping protection circuit and operated when the base current is 10mA (TYP).
