What is a tda2003 IC?

The TDA2003 is an Audio Amplifier IC from ST Microelectronics with a maximum output power of 10W commonly used in stereo amplification in car Radio. The IC can output a maximum current of 3.5A and features very low harmonic and crossover distortion. Note: Complete Technical Details can be found at the datasheet give at the end of this page.

How many Watts Does the tda2003 stereo amplifier output?

With this power supply, the TDA2003 stereo amplifier will output about 7 Watts into 2 Ω speakers, and the bridged amp will output about 14 Watts into 4 Ω speakers.

What is the function of pins 5 and 3 on tdatda2003?

TDA2003 is a 5-pin IC amplifier. The pins 5 and 3 are used to power the IC amplifier, and the audio signal to be amplified is given through pin 1 which is a non-inverting input. Amplified audio output can be achieved through pin 4. The values of the components given above are the values recommended by manufactures.

How can I make the tda2003 quieter?

The TDA2003 can be a bit tricky when it comes to grounding. Poorly designed grounding layouts are a common source of noise and hum. To keep hum to a minimum, the high current power supply and output grounds should be kept separate from the input and feedback loop grounds. This can be accomplished using a star ground.
