Key Features

  • as above described. 3. Pin 2 control (second amplifier stop control function) Pin 2 is a pin to turn ON/OFF the operation of second amplifier. By using this function, the pop sound at startup can be reduced. Note that pin 2 can be controlled by applying the voltage described below : Second amplifier ON ⇒ V2 = 1.6 to VCCV or OPEN Second amplifier OFF ⇒ V2 = 0 to 0.3V When the pin-1 capacitor C4 is downsized, the pop sound becomes louder. The pop sound can be reduced by providing the time Tmu to s.
