(6) Switching pins
(a) PW SW
The device is ON when this pin is set to High. To prevent the IC being turned ON by external noise, it is
necessary to connect an external pull-down resistor to the PW SW pin. The pin is highly sensitive.
(b) MUTE SW
If the MUTE SW pin is fixed to High, current will flow through the pin, even when the PW SW pin is in
OFF Mode. To prevent the IC being turned ON by external noise, it is necessary to connect an external
pull-down resistor.
The pop noise heard when the MUTE SW switch is turned ON or OFF can be reduced by connecting an
external capacitor to the MUTE TC pin.
