Current dissipation that is a sum of V 1 and V 2 at no load. CC CC *2. Input AMP is a BUFFER AMP. *3. Voltage difference between both ends of load (8). Output saturated. *4. Voltage difference between both ends of load (12). Output saturated. *5. The source of input OP-AMP is a constant current. (See the specified block diagram.) As the 11k 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.
