Features and Usage Notes
Pin 5 is the standby switch pin. The amplifier is turned on by applying approximately 2 V or more to this pin through an
external resistor (R1). The current flowing into pin 5 is 500 µA or less.
Pin 6 is the mute pin. The amplifier on time can be set as desired through C3. By grounding pin 6, the amplifier can implement
mute operation. In this case, the recovery time depends on C3.
In order to prevent damage or degradation which may be caused by abnormally heated IC, the LA4705 has a thermal shutdown
protector. Accordingly, in the case of inadequate heat dissipation, the thermal shutdown protector will operate to control the
output gradually into attenuation.
Also be fully careful of handling other protectors built in the LA4705.
