7 Watt Audio Amplifier Circuit
No matter how much volume, an audio amp provides, there are still those who require even more. The circuit in Figure 4 uses a LM383 IC amp and will provide up to 7 watts of output power for those who want to really experience their audio.
The LM383 comes in a TO220 type package with 5 pins. This IC  must be heat sinked at all times due to its high standby current. If you plan to use this IC keep all components as close as possible to the IC and be certain that your power source can supply up to 1.3 amps of current.
The main advantage to this IC is its 7 watt output which is why it has found its way into many inexpensive car radios.
This IC offers low distortion and is a real bargain compared to discrete transistors.
High current capability (3.5A) enables the device to drive low impedance loads with low distortion. The LM383 is Current Limited and thermally protected. High voltage protection is available (LM383A) which enables the amplifier to withstand 40V transients on its supply. The LM383 comes in a 5-pin TO-220 package. By National Semiconductor Corporation
