Help need for Audio Amplifier LA4440 IC

Overvoltage, surge voltage protector c. Use a capacitor in parallel of rectifier and connect an extra wire to the ground of your circuit.

This catalog provides information as of February, Low distortion over a wide range from low frequencies to high frequencies. The AD provides low noise 2.

If your speakers and music source are half decent then an datadheet is not needed. A heat sink of good la datasheet must be used with LA IC.

If you connect an 8 Ohm speaker to this amp its output will be reduced to 9. You must log in or register to reply here.


The datasheet for the obsolete LA amplifier IC shows that its input resistance is 80k ohms so a 10k or 20k logarithmic audio taper volume control should be used. A very high quality circuit with respect to its cost and ideal for beginners. I have a double ic board it was working fine but one day it stop working when I connect power supply to the board the supply wire get hot please tell me the solution of the problem.

The IC also incorporates a audio muting function, but that is not used here. When applying grease on the junction surface, it la datasheet be applied uniformly on the whole surface lead pins are soldered to the printed circuit board after the radiator fin is mounted on the IC.

Datasheeet starter learning Start date Dec 16, And its better working. IC can with stand up to 25 volt, but I prefer it should not be nothing more than 16V.
