Pcb Tda 2003

If you are further interested in tda2003 related topics i have another post car audio amplifier using tda2003.

Pcb tda 2003. This is power amplifier circuit using the popular tda2003. Use 18v dc for powering this circuit. It s typically used for car audio amplifiers but it also works great as a bedroom amp or anywhere else you need good audio without tons of power. Tda2003 is a cheap amplifier that is designed to run on single rail power supplies unipolar.

Tda2003 must be fitted with a heat sink. Stereo and bridged amplifier pcbs are available for this project. 10w car radio audio amplifier tda2003 datasheet tda2003 circuit tda2003 data sheet. The ic can easily deliver 10w to a 4 ohms load speaker.

But this circuit adapted for use at home by listening to change power supply to 18 volts. The tda2003 is a low cost audio chip amplifier that can put out some really nice sounds. Input ground and output ground must be properly decoupled. Tda2003 10w car radio audio amplifier.

A three pin header is used as audio input and screw terminals are present at supply voltage port and audio output ports. Tda2003 stereo amplifier pcb outline. Pcb layout for this circuit can be found on the datasheet of tda2003. It provides a high output current capability up to 3 5a very low harmonic and cross over distortion.

I designed the pcb in kicad as a single board of 35 by 85 millimeters that holds both channels. Which it uses the supply voltage from 12 volt car battery. Tda2003 stereo amplifier schematic. Tda2003 stereo amplifier design tutorial the pcb and schematic project files.

Speaker k1 can be a 4 ohm one. If the supply voltage peaks to more than 40v then an lc filter must be inserted between the supply and pin 5 in order to assure that the pulses at pin 5 will be held within the limits shown in fig.
