*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. Output ON with MUTE: [H] and OFF with MUTE: [L] (HI impedance).
*5. The source of input OP-AMP is a constant current. As the 11kΩ resistance to the next stage is a load,
pay due attention when setting the input OP-AMP gain.
*6. With VIN1-SW: [L], the input AMP selects AMP-A while VREF selects internal VREF (≈2.5V).
With VIN1-SW: [H], the input AMP selects AMP-B while VREF selects external VREF (≈2VREF-IN).
*7. Voltage of upper (SOURCE) + lower (SINK) sides. At forward/reverse, the output voltage is determined by
subtracting this voltage from VCC.
*8. Short (GND) brake used. SINK side output ON.
*9. 5VREG incorporates a drooping protection circuit and operated when the base current is 10mA (TYP).
