How to Build Your Own 10-Watt Power Amplifier Using an IC TDA 2003

Why we should use this? It is the normal operation of the integrated circuit, the music amplifier for car audio radio sound. Which uses a supply voltage from a 12V car battery. But this circuit is adapted for use in a home. With changing the power supply voltage to 18V.

Cre photo: Exiron. We will notice how the 8 watts only applies to a 4 ohms speaker. And, results when the applied voltage VS is about 18V.

The volume is quite sufficient for the people in the assembly room and the volume control was only about half. 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.

See in the circuit below we will learn how it works. The output power is more than about 10 watts RMS. The external components required for the power amplifier are either for feedback, decoupling or high-frequency suppression. C1: The 4. It is designed to AC couple the amplifier to a source such as a tuner or any audio signal.

The C7 is a storage capacitor for supplying high currents during peak passages. And, it also reduces the power supply ripple.

The C6 capacitor is quite important. It can prevent a form of oscillation from occurring at risky power supply impedance levels. The C3: 0. The value of C is designed to set the upper-frequency cut-off. The R1 also sets the high frequency cut off point and if reduced in value, oscillation may occur. The actual gain of the amplifier is set by the ratio of the ohm resistor and 2. When entering the power supply 15 volts to the circuit.

The C1 coupling audio signal through the VR1 to adjust the volume. The non-inverting amplifier circuit is a non-return phase. This is the signal output pin 4, by a C5 enhances the stability of low-frequency response the better. And the noise will be dropped down to the ground by R4 and C6 before outputting to speakers. Another part of the output signal, which is fed back through C3, and R1, to enter the pin 2 inverting. To maintain a constant frequency response at-3dB.

And if you want to add. The frequency response is to reduce the C3. The C8 is a filter file before the operation. C7 cut out noise from the supply. If you want a stereo amplifier,Is to create an additional set. I found that the gain section limits the amplifier from performing truly.

So I used a 1k resistor with a uf capacitor to ground from pin 2. I always try to make Electronics Learning Easy. C3 in your schematic is microfarad, which is way too large. A better value would be about 39 nano farad. Do the math, what do you think the gain will be with this capacitor? Too low. We have a project on amplifiers for our finals and this schematic worked out fine and dandy! Cheers mate! I am still in the process of studying electrical, however I found that the gain section limits the amplifier from performing truly, so i used a 1k resistor with a uf capacitor to ground from pin 2.

I can share my schematics if allowed. Hello Mark, Oh. You are a great student. You learn and try and improve the circuit. I like TDA, it is a good audio amplifier chip. Is easier for you to send me the circuit? Hi, I use this amplifier with an audio transformer instead of the speaker to transmit music over a long distance.

The transformer has an 8 ohm primary and a secondary that brings the signal to 50 vpp; another audio transformer at the other end drives an 8 ohm speaker. Everything works fine but I would need to control the gain so that the amplifier output remains at a constant level regardless of the amplitude of the incoming audio signal.

I was thinking of using a resistive optocoupler to change the gain but I have no experience on the correct way to use it, can you help me? Thank you. Your email address will not be published.

See at the power rail has a C7: 1,uF electrolytic and C6: 0. And a larger value of C3 will reduce the maximum frequency. Related Posts. Apichet Garaipoom. I love electronic circuits. I will collect a lot of circuit electronics to teach my son and are useful for everyone.

The IC can output a maximum current of 3. Note: Complete Technical Details can be found at the datasheet give at the end of this page. TDA is a general-purpose 10W amplifier IC that can be used in stereo or mono audio design circuits. The amplifier can output upto 3. It can also handle short circuits in both AC and DC rail without killing itself.

I built about a dozen different audio amplifier circuits with the LM but most of them had way too much noise, popping, and other interference. I added a bunch of extra capacitors to reduce the noise, and I added a bass boost control as well to make it sound even better. But before we start building, it might be helpful to get a little background information first…. The LM is quite a versatile chip. Only a couple resistors and capacitors are needed to make a working audio amplifier. The chip has options for gain control and bass boost, and it can also be turned into an oscillator capable of outputting sine waves or square waves. The actual output power you get will depend on your supply voltage and speaker impedance. The datasheet has graphs that will tell you. I used a 9V battery for the power supply and it works great, but you can go down to 4V or up to 12V.

Low Power Audio Amplifier Using IC LM 386

Here is a simple watt audio amplifier using IC LM The IC has five pins and can deliver a maximum of watt output power depending upon the supply voltage and load. The circuit diagram of the audio amplifier is shown in Fig. Connect 15V battery and switch on S1.

Simple Siren Enhancer Circuit 10Watt Using IRF9540

Lower power audio output required systems can use this 10 watt audio amplifier circuit, it requires few external components and low space circuit construction. LM is monolithic power amplifier offering very low distortion, this IC can deliver upto 30 watts when we use 30V bias. It has thermal protection and internal output protection diodes. It comes in TO package. IC LM has only five pins, here two are input terminals, one is output terminal and remaining two for bias. Here audio input signal is applied to the Non inverting input terminal Inverting input terminal is connected between feedback Resistor R3 and to ground supply through R2, C1 elements.

CONSTRUCTION OF A GUITAR AMPLIFIER

Circuit Connections —. This IC is basically an operational amplifier whose voltage gain can be adjusted by using a proper RC circuit between its gain setting pins. If the gain setting pins are left open, the voltage gain of the amplifier is internally set to 20 26 dB. For adjusting the gain between the desired range of 20 26 dB and 46 dB , a variable resistor Shown as RV2 in the circuit diagram of 4. For controlling the output volume level, a variable resistor Shown as RV1 in the circuit diagram is connected at the input of the non-inverting pin. This variable resistor actually changes the amplitude input voltage level of the input signal as amplitude defines the loudness of the audio signal. While assembling this circuit following precautions must be taken care of —. So, with a supply voltage set to 12V and a load of 8 ohms at the output, the power output of the amplifier can be approximately 1 Watt.

I will show some quite common, easy to make and generally low cost. Most of these amplifiers are used by televisions, test and measurement equipment, old modems, etc. Then someone may think that a watt amplifier per channel is low power when in fact it is not because here we talk about real power or RMS. You should know that PMPO is not a real electronic measure.
