Here is the schematic for an 8 watt audio amp. This amp can be used as a simple booster, the heart of a more complicated amplifier or used as a guitar amp. |

| im doingin a project on 60watt audio amplifier,how do i go about it? | ||
| the circuit is wrong,pin numbers do not match the specification sheet | ||
| Pl Chek LM383 Pinout. Pin No .4 is Ground. But Curicuit Pin No. 04 is OutPut. It Rong. | ||
| This IC is obsolete and has not been made for 12 years. The pins numbers on the schematic are completely wrong. The schematic is missing important parts. Make the circuit on the datasheet of the TDA2003 instead. It is available, shows all the parts and even shows a pcb design. | ||
| can u send to me the explanation and calcution for this circuit | ||
| i am invovled in a project on 60watt audio amplifier,how do i go about it? | ||
| its a great amp and really useful but rubish too | ||
| there is no volume controller | ||
| Very useful little circuit, built it out of spare parts in just a few minutes. I'm listening to it right now. Not really hi-fi, but with standard components its more than good enough for something like a table radio, car amplifier, or PC speaker system. It has more than enough juice to power most full range speakers, and only takes up about two square inches of board space. It works best with 4Ù speakers, but is capable of driving 8Ùs as well. I STRONGLY recommend against building this without adding an 0.22 µF capacitor and 1Ù resistor in series from the input of C4 to ground (See LM383's datasheet), failing to do so will send the circuit into a potentially destructive oscillation. Also, be sure to check the datasheet (http://www.datasheetcatalog.com/) for your specific manufacturer and model of IC, the pinout may be different depending on the chip's manufacturer. The current production version of LM383 is NTE's NTE1232 IC, which will also work well in this circuit. | ||
| GREAT CIRCUIT but for c3 i would use a 2200uf cap instead of .1uf capacitor the .1 cap blew up on me lol | ||
