(Precaution 1)
When the standby terminal was put to the low level after the ripple rapid discharging circuit was operated
(VCC≒8V) at the time when VCC was turned off, a pop noise may be generated. Therefore, VCC which makes
the standby terminal low shall be set at 8V or above so that (1) the standby terminal is put at the low level
and (2) the ripple rapid discharging circuit is turned on when VCC is turned off (in order of (1) and (2)). An
example of application is shown in Fig.9.
(Precaution 2)
If the falling time constant of the VCC line is large (the fall is gentle), the pop noise may become worse.
In this case, it is possible to prevent the pop noise from becoming worse by reducing the ability of “ripple rapid
discharging circuit at the time of VCC off” according to the increase of the capacity of ripple capacitor of pin(8).
However, it shall be kept in mind that the time for turning the power on becomes longer as the result of this
method.
