Low-cost application

In low-cost applications where the microprocessor is not present, the recommended circuit

is shown in Figure 5.

The st-by and mute terminals are tied together and they are connected to the supply line via

an external voltage divider.

The device is switched on/off from the supply line and the external capacitor C4 is used to

delay exceeding the st-by and mute threshold in order to avoid "popping" noise.
