(B) Low Cost Application
In low cost applications where the mP is not pre-
sent, the suggested circuit is shown in fig.3.
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 intended to delay
the St-by and mute threshold exceeding, avoiding
”Popping” problems.
