TDA2003 is my favorite audio amplifier integrated circuit chip in 10 Watt class. All you need is just adding few passive components and your amplifier will be ready. You can even amplify ultrasonic range if you wish to abuse its usage, just to convince you that this chip is more than enough to handle any range of audio signal. Although many manufacturer produce this TDA2003 chip, in general, this various chip from various manufacturer normally comply with these following features: Short circuit protection between all pins, High current output ( up to 3 A), Built-in Over temperature protection, and Low harmonic and crossover distortion.
