![]() ![]() See in the circuit below we will learn how it works. Once these limits are reached, the distortion level increases rapidly to 10%.Īnd at this level, the average person can noticeably hear that something is wrong. In fact, the amplifier has very good figures up to 8 watts with a 2 ohms speaker and 6 watts with a 4-ohm speaker. In the datasheet, If you use 14.4V of VS. The figure distortion up to 5 watts is 0.2%. The clarity and bass response was exceptional. The volume is quite sufficient for the people in the assembly room and the volume control was only about half. We may place four 8 ohm speakers in parallel to output. This feature is a good side, right? It means that you can parallel: Then, if we change load is an 8 ohms speaker, the power is practically halved. We can use load is 1.6 ohms to 4 ohms speaker impedances. And, results when the applied voltage (VS) is about 18V. We will notice how the 8 watts only applies to a 4 ohms speaker. It shows the relationship between power out and applied voltage. The maximum output power and relationshipĭo you want to know the output power of this chip? If, Yes look at the graph below. Then, see its Circuit connection or symbol below. ![]() Pin 3 of IC1 is connected to ground.Cre photo: Exiron TDA2003 Pinout and symbol The audio frequency (or audio signal) is fed to pin 1 of IC1 through the combination of a 10-kilo-ohm potmeter (VR1) and capacitors C1 and C2. Pin 1 of TDA2003 is the input terminal, which is connected to ground through a 100-kilo-ohm resistor.

It has protection against short circuit of DC and AC, thermal protection over the allowed range, dump of the load voltage peaks of up to 40V and accidental earth breaks. The TDA2003 provides an output current of up to 3.5 A, very low harmonic or cross-over distortion. ![]()
