TDA2003 (10W Audio Amplifier)

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
