... Ordering number: EN3848D Overview The LA4705 is a BTL two-channel power IC for car audio and radio-cassette players developed in pursuit of excellent sound quality. Low-region frequency characteristics have been improved through the use of a new NF capacitorless circuit, and crosstalk which causes ‘‘muddy’’ sound has been reduced by improving both circuit and pattern layout ...

... In this case, the recovery time depends on C3 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. ...

C5 Power supply capacitor C6, C7, C8, C9 Oscillation blocking capacitors R1 Standby switch current limiting resistor LA4705 Copper foil area 90 2.2 µF is recommended. f can be varied by C1, C4 capacitances to adjust the L bass range. Approximately 0.6 to 0.7 second for 33 µF. Since the on time is proportional to this capacitance, it can be set as desired by varying this capacitance. The amplifier can implement mute operation by setting C3 to GND potential ...
