[Feature]
• The pop noise which occurs to the time of power supply on/off can be improved substantially by recommendation
Stand-By Control Application.
• Stand-By Control can be done by additionally adjusting the limitation resistance to the voltage such as miccom, the
set design is easy.

[Operation explanation] #13pin Stand-By Control Voltage VST
(1) Operation Mode
The switching transistor in the bias circuit turns on and places the amplifier into the operating mode, when 13pin
(VST) voltage added above 2.5V (typ 3.0V).
(2) Stand-By Mode
When 13pin (VST) voltage is stopped (= 0V), the switching transistor in the bias circuit turn off. placing the
amplifier into the standby mode.
(*1) The current limiting resistor must be used to ensure that stand-by pin (13pin) voltage does not exceed its
maximum rated value VST max.
(*2) The pop noise level when the power is turned on can be reduced by setting the time constant with a capacitor
in operating mode.
(*3) Determines the time constant at which the capacitor (*2) is discharged in stand-by mode.
