Tda2030 5 1 amplifier circuit diagram

An audio amplifier is nothing but one that has the capability to amplify the audio signals from any audio source such as mobile phone jack or microphone so that volume is increased when the audio is played in a speaker. Audio amplifier circuits can also be made using simple op-amps, but if you need higher volume that is loud enough for a room then this power audio amplifier is will be the best choice. The TDA is breadboard friendly and hence can be easily tested using a breadboard. The TDAA datasheet given at the bottom of this page consists of some basic circuits which can be used to make this IC work. I have also given a very basic circuit below.

An impressive watt amplifier circuit can be built by cascading a couple of TDA IC in a bridged tied load BTL configuration and through a few current boosting transistors. The main objective of a BTL configuration is to enable a two way operation of the load which in turn helps to increase a two fold increase in the efficiency level of the system.

It's equivalent to a full bridge network which we normally find in inverters. IC1 and IC2 are the two TDA ICs rigged in a bridged tied load configuration which means the these two IC s now conduct in tandem in response to the high and low amplitudes of the input frequency and drive the loudspeaker in a powerful push pull mode. For example when IC1 output may be delivering a high output to the speakers, IC2 simultaneously would be delivering a low output and vice versa enabling the required push pull action on the loudspeaker.

This means the loudspeaker would be alternately operated with maximum positive and negative supply levels, causing the loudspeaker to work with double efficiency level compared to the normal amplifiers which are not BTL based. The various resistors and capacitors around the speaker are introduced to suppress and filter the final outcome on the speaker, and to produce a clean and distortion free audio on the speaker.

If you have any circuit related query, you may interact through comments, I'll be most happy to help! Your email:.

I would want to use it for car audio since its single railed. Normally removing the transformer and the power supply stage should do the trick but I realize in this circuit the transformer center tap has made a few connections, IF I was to to run this from just a 12v battery that means I could just replace the center tap connections with battery negative?

No that may not be possible, you will have to use two 12V bats in series, and use the series joint as the ground for the amplifier, this will replace the center tap rail of the trafo. Hi Swagatam, hope you are doing well. Thank you.

Hi Lima, it is watt RMS, because along with the IC the load is also handled by the external BJTs, which allows the design to run the specified amount of power continuously without any problems. You are most welcome Lima!! Yes it is. I have checked their datasheets and they are almost same, the only difference is TDA has a higher input voltage and more wattage power on the output. I have built d this same cct with all d component stated but I found out that on d connection of d speaker something is wrong.

I will update the circuit soon with a capacitor…thank you for this useful information. Hi Swagatam please send modified updated ver of this Amplifier With capacitor in series and lm also works well. Thanks Waqar, I do not have much idea about the other IC, if you think the pinouts are similar, you can try configuring them in the same fashion as above and see if it works, ….

I am not getting bad series transistor……. Hi swagatam. I am not getting bd series transistor….. Hi Waqar, Any transistor will work, just make sure the emitter-collector voltage and the maximum current handling capacity of the transistor are adequately higher than the maximum supply voltage of the amplifier. Q1, Q2 can be together on a heat zinc and Q3 ,Q4 on another zinc also different heat zinc for each ic. I wish u good luck…please u cn add it up in d write up swagatam.

I Don build toggle switch with ic. However switch should be always at the primary side so that the transformer also gets switched off, otherwise your transformer will be always ON and consume some current even while the amp is switched OFF, so it is better to put the switch at the primary side only….

I have a reason with you. I make small transformerless cct to power the relay and ic and make the switch at the primary side. DPDT relay is not available yet. I understand what you are saying. I make the switch at the primary side but I build a transformerless circuit to power the relay and ic. It is a standard electrolytic capacitor, it is positioned to stop overloading of the speaker and to block DC from entering the speaker.

Is there any watt amplifier in your box. Sorry to sidetrack the discussion, but I found this after a lot of searching, and the setup intrigued me some. So if you have the time and chance to help me understand this, I would greatly appreciate it. I would like to try building it, though I realize some of the values are a little cryptic to me.

So I liked to ask to make sure; L1 — 3. L2 — C1 — Though I am not familiar with counting Capacitors by ohm? C2 — R1 — The design was taken from elektor electronics magazine so most probably this would work as intended.

I very much enjoy these informative posts, Swagatam. I have an 18v split supply and want to use just one side of this bridged configuration, single op amp and pair of output transistors with the other side of speaker connected to center tapped ground.

Either schematic it appears both transistors are wide open at all times with diodes blocking what could possibly be a constant dc current drain? Not sure exactly how this circuit works, I am new to this field. I am guessing that the output of the IC from pin 4 in any positive range gets amplified through the npn power transistor, while negative signals get amplified through the pnp power transistor via power thresh-hold at their emitters.

Honestly, I have always found it tough to understand audio amplifier circuits and their configurations, the same goes for this design too. The only vital thing I know about it is that its a BTL type of amplifier which works in a push pull manner for maximum efficiency. For your present requirement I think the first diagram from the following article might help. It shows a simple design for using an opamp to drive a loudspeaker via a couple of driver transistor.

Mr swagatam, please advise me on which circuit I can go for. I need an amplifier circuit that can be used in a room of 25 x25 m night club. Hi Emmanuel, you can try the following circuit, you will have to make two of them for a stereo effect:. Please am a first year student in computer engineering, I have a project work to build an amplifier. Can you help me out? Your email address will not be published.

Notify me via e-mail if anyone answers my comment. You'll also like: 1. Thanks…a lot……send some project for microcontroller burners.

I will do some online search and update it if I happen to find the required design…. Thank you very much Jesubiyi, appreciate your concern and the notes…. The ohm is a typo, it is supposed to be mH. Thanks John, Glad you are liking my work! Hello, what is the quality of audio compare to TDA What would be your personal preference? Hallo am happy to be here.

Audio Amplifier Using TDA2030A


Class D amplifiers, first proposed in , have become increasingly popular in recent years. What are Class D amplifiers? How do they compare with other kinds of amplifiers? Why is Class D of interest for audio? Find the answers to all these questions in the following pages. The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels—faithfully, efficiently, and at low distortion. Audio frequencies range from about 20 Hz to 20 kHz, so the amplifier must have good frequency response over this range less when driving a band-limited speaker, such as a woofer or a tweeter.

Meanwhile somehow I still have four TDA ICs maybe I bought these chips about 10 years ago and simply forgot to use in my parts inventory. Practically operational amplifier schematics can be found in the technical document of STMicroelectronics. For example, the following web page shows diverse and detail instructions for making amplifier with the TDA chip. The followings are slight modifications from original schematics recommended by STMicroelectronics. Above modifications are not much critical and just included as personal preferences such as having visual LED power indicator, and anticipations for preventing high frequency noise from power supply lines by using additional 0. But using more high capacity of parts such as uF and uF seems to make audio output quality more dynamic. Maybe it can be personal impression. Therefore, several modifications mention above can be safely omitted when you want to make overall amplifier circuit simple.

Connect a 22k log volume control cold end to ground slider to C1 and the other end and common to signal source. I thought I would try to make a small guitar amplifier using some of the circuit designs posted here.

This amplifier circuit require less external components too, making it easier for a beginner to make this on Veroboard or Perf Board. This can be operated with single supply line, but that topology gives less output power, hence this bi-voltage topology is used everywhere. The filter capacitor is usually uF to uF, we can use even bigger capacitor for better results. I made audio amp circuit using tda a ic.
