*1. Total current consumption of VCC1 and VCC2 when non-load.
*2. Input AMP is BUFFER AMP.
*3. Voltage differences between both ends of load (8Ω). Output is saturated.
*4. When MUTE is "H", output is ON. When MUTE is "L", output is OFF (HI impedance).
*5. Input OP-AMP SOURCE is constant current. Since 11kΩ resistance to the next level is loaded,
100 mV
special care should be taken for the gain setting of input OP-AMP.
*6. When VIN1-SW is "L", select AMP-A for input AMP and internal VREF (nearly equal to 2.5V) for VREF.
When VIN-SW is "H", select AMP-B for input AMP and external VREF (nearly equal to VREF-IN) for VREF.
*7. Voltage of upper side (SOURCE) and lower side (SINK). For Normal/Reverse rotation. Output voltage is obtained
by subtracting this value from VCC.
*8. Brake is short (GND) brake. Output of SINK side is ON.
*9. 5VREG has built-in dropping protection circuit. Operates when base current is 10mA (TYP).
