Cautions

Oscillation of the capacitor between the output pin and GND may cause oscillation. In such an event, insert 0.1

μF

+2.2

Ω between pins 1 and 3.

1. Rise and fall of AMP VCC (2Pin), Mute (6Pin)

• When raising AMP, always raise the Mute pin 6 in 1sec after the VCC pin 2.

• When falling AMP, always fall the VCC pin 2 in 1sec after the Mute pin 6.

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 50

μA when VMute is 5V and RMute 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.
