LA4705
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.
