The devce provides a high output current capability. /rebates/&252ftda2003-pcb. The additional features of TDA 2002, very low number of external components, ease of assembly, space and cost saving, are maintained. With changing the power supply voltage to 18V. But this circuit is adapted for use in a home. Which uses a supply voltage from a 12V car battery. Why we should use this It is the normal operation of the integrated circuit, the music amplifier for car audio radio sound. ® TDA2003 10W CAR RADIO AUDIO AMPLIFIER DESCRIPTION The TDA 2003 has improved performance with the same pin configuration as the TDA 2002. See, this is a TDA2003 amplifier circuit, popular IC from SGS Thomson.Power output: 6W into 4 ohms at 10% 1kHz distortion with power supply 14.4V Power output: 10W into 2 ohms at 10% 1kHz distortion with power supply 14.4V Power output: 4.5W into 4 ohms at 0.15% 1kHz. TDA2003 application Quick facts TDA2003 / TDA2003A. Recommended Experience: lower intermediate, knowledge of amplifiers, PCB etching, heatsink attaching, and (optional) mains qualification.It can also handle short circuits in both AC and DC rail without killing itself. The amplifier can output upto 3.5A current to drive speakers and can also handle high current upto 5A for shorter duration without any damage.
