Introduction to TDA2003 TDA2050 is a general-purpose 32W amplifier IC that can be used in stereo or mono audio design circuits. The amplifier can output upto 5A current to drive speakers without any damage. It can also handle short circuits in both AC and DC rail without killing itself. It has an operating voltage of ±25V allowing it to operate in both single and dual supply voltages. This makes it robust to be used in automotive audio designs. The TDA2050 is breadboard friendly and hence can be easily tested using a breadboard. A sample application circuit for TDA2050 is given below. The tda2050 datasheet given at the bottom of this page consists of more details on this design. TDA2050 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. Note that this IC has currently become obsolete and is no longer in production, though you can find few clones being sold in the market by different manufacturers. For new designs the replacement ICs like LM1875 from Texas Instruments. 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 TDA2050 Datasheet
