Circuit power amplifier audio with circuit integrated lm383 / lm38A

Lm383 although it is not a ic of new audio, it is a good option for who wants an amplifier easy to set up and it demands few external components for your implementation. when the lm383 was developed it was designated for applications automotive. But you can use that ic in varied audio projects as amplified boxes, amplifier for guitar among other applications.

Principal characteristics of the IC lm383

– High current capacity (3,5 THE)
– Strip of feeding tension: 5 TO 18 V
– Input Impedance: 150 k ohms
– Strip passer-by: 30 kHz
– Harmonic Distortion Total : 0,2% (tip)

  1. it is true that this chip is not being in production?build several of this amps for past years but this time,the chips always blows or overheated,so i try the tda2003 instead of lm383,maybe there is a fake lm383 in circulation,hope you post other new circuit,more power to you
