3 W BTL audio amplifier

8.2 Mode select pin (MODE)

The device is in Standby mode (with a very low current consumption) if the voltage at the

MODE pin is greater than VCC − 0.5 V, or if this pin is floating. At a MODE voltage in the

range between 1.5 V and VCC − 1.5 V the amplifier is in a mute condition. The mute

condition is useful to suppress plop noise at the output, caused by charging of the input

capacitor.
