The devce provides a high output current capability. But this circuit adapted for use at home by listening to change power supply to 18 volts. Tda2003a is a 5 pin audio amplifier ic.

Speaker k1 can be a 4 ohm one. Which it uses the supply voltage from 12 volt car battery. Tda2003 10w car radio audio amplifier description the tda 2003 has improved performance with the same pin configuration as the tda 2002. The tda2003 amplifier on homemade pcb without heatsink.

Anfi circuit ne5532 lm393 lm393 op amp fan and temperature controls have on the circuit board pcb layout pcb drawing program with sprint prepared for imaging and print output can use the free sprint layout viewer program. Tda2003 is a cheap amplifier that is designed to run on single rail power supplies unipolar. The tda2003 is a low cost audio chip amplifier that can put out some really nice sounds. Tda2003 must be fitted with a heat sink.

The ic can easily deliver 10w to a 4 ohms load speaker. Stereo and bridged amplifier pcbs are available for this project. The additional features of tda 2002 very low number of external components ease of assembly space and cost saving are maintained. Tda2003 10w car radio audio amplifier.

If you are further interested in tda2003 related topics i have another post car audio amplifier using tda2003. 4558 tone control schematic. I designed the pcb in kicad as a single board of 35 by 85 millimeters that holds both channels. Use 18v dc for powering this circuit.

It provides a high output current capability up to 3 5a very low harmonic and cross over distortion. 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. The pins 5 3 power the amplifier ic and the audio signal to be amplified is given in through pin 1 which is the non inverting input. Pcb layout for this circuit can be found on the datasheet of tda2003.
