Introduction to TDA2003
TDA2003 is a general-purpose 10W amplifier IC that can be used in stereo or mono audio design circuits. 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. It can also handle short circuits in both AC and DC rail without killing itself. It has an operating voltage of 18V but can handle high voltage up to 28V. This makes it robust to be used in automotive audio designs.
The TDA2030 is breadboard friendly and hence can be easily tested using a breadboard. A sample application circuit for TDA2030 is given below. The datasheet given at the bottom of this page consists of more details on this design.
TDA2003 is a 5-pin Amplifier IC. The pin 5 and 3 are used to power the Amplifier IC, and the audio signal to be amplified is given in through pin 1 which is the non-inverting input. The amplified audio output can be obtained through pin 4. The values of the components given above are the values recommended by manufactures. The two important components are the Cx and Rx which sets the bandwidth for the amplifier using the formulae shown above. Also the Resistors R1 and R2 are used doe setting the gain of the amplifier.
Applications
- Used for Audio signal Amplification
- Suitable for high power amplification
- Capable of operating on dual/split power supply
- Can be used to cascade audio speakers
2-D Model (PDIP)
If you would like to build a HI-FI power amplifier project that power output size about 30 watts to 50 watts or 75 watts at 8 ohms loudspeaker, and is high-quality sound and easy to build (not too many components).
We recommend you use TDA2050 class AB OCL amplifier circuits. Below that builds with the integrated circuit, PCB layout and no need for any customization. Parts used in this circuit are easily available in most of the local markets.
TDA2050 datasheet
The TDA2050 is class AB audio amplifier. Its high power capability the TDA2050 is able to provide up to 35W true rms power into speaker 4 ohm load at THD =10%, VS =±18V, f = 1KHz and up to 32W into 8ohm load @THD = 10%, VS = 22V, f = 1KHz.Moreover, the TDA 2050 delivers typically 50W

50W-75W Stereo power amplifier using TDA2050
We used the TDA2030 to build many power amplifier projects, but they have lower power than 30 watts.
Today, we try to use the TDA2050, which has the output power about 50 watts that shape and easy to use as well.
This project is stereo that easy to builds can adjust volume, tone and balanced sound.
First of all, we look at the circuit diagram below.
This circuit with a high current so takes low voltage 25V similar the normal 30 watts amplifier.
Figure 1: the 35W + 35W stereo power amplifier circuit using TDA2050
We should use the 25V CT -25V high current power supply circuit with RFI filter system. Which have 4 x 2,200uF 50V are connected together in parallel.
Figure 2: the 25V CT -25V Dual power supply of this projects
Disguise your voice to trick your friends. 
We can boost up power output to 75 watts by the same voltage power supply.
In the circuit, we use both transistors 2N3055 NPN types and MJ2955 PNP type to increase current up.
