LA4440 is an integrated circuit (IC) audio amplifier that is widely used in various electronic projects, especially in audio systems.

The device has various built-in protection features, including overcurrent protection, thermal shutdown, and short circuit protection. It also has a low distortion and a high signal-to-noise ratio, making it an ideal choice for high-quality audio applications.


1. Built-in 2 channels (dual) enabling use in stereo and bridge amplifier applications.

(1) Dual : 6Wx2 (typ.)

(2) Bridge : 19W (typ.)

2. Minimun number of external parts required.

3. Small pop noise at the time of power supply ON/OFF and good starting balance.

4. Good ripple rejection : 46dB (typ.)

5. Good channel separation.

6. Small residual noise (Rg=0).

7. Low distortion over a wide range from low frequencies to high frequencies.

8. Easy to design radiator fin.

9. Built-in audio muting function.
