Description of external parts
C
C
C
: Input coupling capacitor, for which 0.47μF is recommended. Since the input pin potential is about 1/2 V
,
IN
CC
the ceramic capacitor with small leak current is recommended.
: Ripple filter capacitor, for which 100μF is recommended. Note that the capacitance below 100μF will cause
decrease in the ripple removal ratio.
: Capacitor for mute.
: Power capacitor.

Cautions
Oscillation of the capacitor between the output pin and GND may cause oscillation. In such an event, insert 0.1μF
+2.2Ω between pins 1 and 3.

• When raising AMP, always raise the Mute pin 6 in 1sec after the V
pin 2.
CC
pin 2 in 1sec after the Mute pin 6.
• When falling AMP, always fall the V

Above procedure will alleviate the shock sound at rise and fall.
2. Mute function (pin 6)
The mute function is turned ON with the pin 6 voltage of 1.0V or less and OFF with the voltage of 2.5V or more.
The inrush current to pin 6 is about 50μA when V
is 5V and R
is10kΩ.

Cautions for use
1. Short-circuit (power – output short-circuit), ground fault (GND – output short-circuit), and load short-circuit
protective circuits are incorporated. They are activated in case of abnormal connection.
These circuits remain active while such abnormal connection continues and is reset automatically when the
abnormality is removed.
2. The thermal protection circuit is incorporated and is activated when the junction temperature (Tj) rises to about 170°C
or more. The output is controlled to return gradually to the attenuated state.
3. When the product is used near the maximum rating, even the slightest change in the condition may cause exceeding of
the maximum rating, resulting possibly in breakdown. Take the sufficient margin for the supply voltage, etc. and
always use the product within a range never exceeding the maximum rating.
