10/30/2023 0 Comments Tda2003 pcbRefer data sheet for more electrical specifications. It is sensitive to minimum 14 mV input signal and provides input resistance 150KΩ. A pair can be used to improve the sound from a NICAM TV, or even one may be used to improve a mono TV. I uses this amp for my centre channel in my. This small amplifier is constructed around the TDA2003 IC. This TDA2003 IC can take supply voltage Vs between 8 to 18 Volts, and gives output power depends on load resistor RL, maximum 10 Watts if RL = 2Ω. tda2005 pcb tda7377 amplifier circuit tda2003 pcb tda2050 bridge amplifier circuit stereo. This TDA2003 amplifier can give upto 20 Watts output when connected in Bridge configuration. Inverting pin of TDA2003 is connected with C3 capacitor and R2, R3 divider Resistors to act as a feedback path, at the output loud speaker is connected through coupling capacitor. Here VR1 is acts as a volume control in this circuit. TDA2003 Amplifier circuit diagram built for 8Ω speaker and this circuit can provide upto 10 watts output, you can apply 6 to 12V power supply to this circuit.Ĭonnect Audio input signal to non inverting pin of TDA2003 IC. This IC has only 5 pins and all are function pins, this Integrated circuit has built in over temperature protection and short circuit protection features. By implementing this TDA2003 IC in a low power audio amplifier we can built low harmonic and cross over distortion amplifier. It requires very low external components to operated as a amplifier and also it can provide high current output. TDA2003 is a monolithic audio power Amplifier integrated circuit.
