A straightforward low power car stereo amplifier circuit taking into account TDA 2003 is showed here.
The circuit utilizes low cost, promptly accessible components and it is anything but difficult to develop.
TDA2003 is an integrated car radio amplifier from ST Micro electronics that has a ton of good elements like short circuit protection for all the pins, heat over range level low harmonic distortion, low traverse bending and so on.
In the circuit given here each TDA2003 is wired as a mono amplifier working from a 12V DC supply. Resistors R2 and R3 shapes a feedback system that sets the amplifier gain. C7 is the input DC de-coupling capacitor and C5 couples the speaker to the amplifiers yield. C4 is utilized for enhancing the swell dismissal or ripple rejection while C1 and C2 are utilized for power supply filteration. C3 and R1 are utilized for setting the upper frequency cut-off. Network containing C6 and R4 is utilized for frequency adjustment and to avoid oscillation.
