Car Audio Amplifier Circuit

Car Audio Amplifier Circuit
         
A simple low power car stereo amplifier circuit based on TDA 2003 is shown here. The
circuit uses cheap, readily available components and it is very easy to construct.
TDA2003 is an integrated car radio amplifier from ST Micro electronics that has a lot of
good features like short circuit protection for all pins, thermal over range low
harmonic distortion, low cross over distortion etc.
In the circuit given here each TDA2003 is wired as a mono amplifier operating from a 12V
supply. Resistors R2 and R3 forms a feedback network that sets the amplifiers gain. C7
is the input DC de-coupling capacitor and C5 couples the speaker to the amplifiers
output. C4 is used for improving the ripple rejection while C1 and C2 are employed for
power supply filtering. C3 and R1 are used for setting the upper frequency cut-off.
Network comprising of C6 and R4 is used for frequency stabilization and to prevent oscillation.
Notes.
Assemble the circuit on a good quality PCB.
Heat sinks are necessary for both ICs.
The circuit can be operated from 12V DC.
S1 is the ON/OFF switch.
