The National Semiconductor LM383 (and its equivalent TDA2003 from other manufacturers) is a proven and successful audio amplifier. It comes in a 5 pin TO-220 package suitable for mounting onto almost any heatsink (unlike DIL packages such as the LM380 & LM386.) Although it operates at low voltage this does not mean low power. It can drive loads as low as 1.6 ohm (5 8-ohm speakers in parallel) yet it is capable of delivering up to 11 watts from a 16V supply. It is an ideal building block for many audio projects. You must supply your own 8W speaker.

The main features of the LM383 include:
- 5V - 20V supply range - current limiting & thermally protected - The chip shuts down if the temperature reaches 150 o C - few external parts required - no turn-on transients
-40 db gain!
