FIG4. Standby Application circuit
Standby pin should be connected with carefully
selected components in order to avoid
“Pop Noise” during Standby ON/OFF transient.
The 51k resistor and 10uF capacitor pair can
delay the rising of voltage at pin 5 to reach the
Standby threshold. When Standby is switching
on together with supply, this delay would be very
useful to ensure no “Pop Noise”.
If the Standby voltage is provided by a microcontroller, the suppression of “Pop” could even
be better.
For further details of timing and delay for standby circuit, please refer to page 11.
Mute operation
Mute pin should be connected with carefully
selected components in order to avoid
“Pop Noise” during MUTE ON/OFF transient.

Mute
The 8.2k resistor and 33uF capacitor pair can delay
the rising of voltage at pin 6 to reach the Mute
threshold. When Mute is switching on together
with supply, this delay would be very useful to
ensure no “Pop Noise”.
