TEST CIRCUIT
(*1) This IC can be used without coupling capacitor (C
If volume slide noise occurred by input offset voltage is undesirable, it needs to use the capacitor (C
(*2) The condenser between the >pin and the GND (C11) is for reducing POP noise when the power ON/OFF
switch (SW1) is set to ON/OFF.
