TDA integrated circuits series are very well apreciated and used in amplifier designs and projects. TDA audio amplifier circuits are produced in generally by Philips and SGS-THOMSON. The most used ICs are TDA2030 and TDA2003 for small audio amplifiers kits and TDA7294 for higher power amplifiers.
In this article we present some representative amplifiers schematics with TDA circuits: car and home audio amplifiers with datasheets below every circuit diagram.

TDA2003 amplifier circuits
TDA2003 is a cheap amplifier that is designed to run on single rail power supplies (unipolar). It provides a high output current capability (up to 3.5A), very low harmonic and cross-over distortion.
TDA2003 10W car radio audio amplifier
TDA2003 bridge 18W amplifier
TDA2003 can be used as an BCL (bridge amplifier) and car deliver up to 18W.
TDA2005 amplifier circuits
TDA2005 is a class B dual audio power amplifier specifically designed for car radio applications. Its high current capability (up to 3.5 A) and the ability to drive very low impedance loads (down to 1.6 ohms) makes this circuit a good choice for cheap power booster amplifiers.

TDA2030 amplifier circuits
TDA2030 is a monolithic integrated circuit in Pentawatt package, intended for use as a low frequency class AB amplifier. Typically it provides 14W output power (d = 0.5%) at 14V/4Ω at ± 14V or 28V, the guaranteed output power is 12W on a 4Ω load and 8W on a 8Ω

TDA2050 amplifier circuits
TDA 2050 is a monolithic integrated circuit in Pentawatt package, intended for use as an audio class AB audio amplifier. Thanks to its high power capability the TDA2050 is able to provide up to 35W true rms power into 4 ohm load @ THD = 10%, VS = ±18V, f = 1KHz and up to 32W into 8ohm load@ THD = 10%, VS = ±22V, f = 1KHz. Moreover, the TDA 2050 delivers typically 50W music power into 4 ohm load over 1 sec at VS= 22.5V, f = 1KHz.

TDA7294 amplifier circuits
TDA7294 is a monolithic integrated circuit in Multiwatt15 package, with high output power (up to 100W) intended for use as audio class AB amplifier in Hi-Fi field applications (Home Stereo, self powered loudspeakers, Topclass TV). Thanks to the wide voltage range and to the high out current capability it is able to supply the highest power into both 4W and 8W loads even in presence of poor supply regulation, with high Supply Voltage Rejection.

i love you patiyo….. very good and clean practical ciruit diagrams! ummma…

TDA Amp is a good choice for low cost. And High Quality Amp.
I like the perfomance of TDA 7384. Its the best!
can u help me schematic diagram of tda 7379..tnx
Tda 2003 is the simplest amp. to make in fact it was my first amp to try. Next let me try Tda 7294 and I will keep you informed of the results.
Ok, thanks for your feedback. I think TDA2003 is a good starting point for every hobbyist. I have seen an amplifier made with TDA7294 and the most import thing was the power source. It must deliver high power and have a very good filter.
i have made a lot of amplifiers,not only TDAs…But i made one with bridged TDA7294 and i have problem with that st-by\mute function…How does it works?
You can connect Stby/Mute to + Vss
can you help me on my amplifier 500watts 2 channel with tda7379 ic..the problem is no sound output….tnx
Thanks for sharing superb informations. Your website is very cool. I am impressed by the details that you’ve on this blog. It reveals how nicely you perceive this subject. Bookmarked this website page, will come back for extra articles. You, my pal, ROCK! I found simply the information I already searched all over the place and just couldn’t come across. What a great website.
surely tda7294′s mute/st by function is alittle bit confusing.am also intrested inRF transmission and reception especially in the UHF and MIcropwave range.could someone out there pliz help especially in circuits using transistors.
I HAVE INHERITED HUNDREDS OF TDA ICS FROM TDA440 UP TO TDA9503 AND SOME TEA’S AS WELL. ANY IDEA WHERE I CAN FIND OUT DATA FOR THESE? I DONT KNOW WHAT THEY DO SO WAS DELIGHTED TO AT LEAST IDENTIFY THE AUDIO AMPS FROM YOUR WEB SITE. WILL BE BUILDING ASAP.
Hi Malcolm, have you found a use for your tda chips? If not, would you like to donate them to a non-profit organization? We teach electronics to poor teenagers, by helping them build amplifiers. Check my website bvhpradio.org/boom. Cheers!
I’ Have made the amplifier with TDA2003 in most case and works, but its very amplified in Bass and Treble
tda7294 is giving very low output. Iam using 24v 2amp DC adapter.
hi guyz im planning to build TDA7294 can you give me the exact size of pdf,
hi;
TDA Amp is Very very Good amplifier and high Quality Amp
TDA is great!!!!
This web site doesn’t show up correctly on my droid you may wanna attempt and repair that
what is full form of tda actually
do you have a pcb layout of tda2005 2×10?
i made TDA 2003 bridge amp acordind to this schematic, and it didn’t work, is thare something wrong whit that?
I assmbled TDA2050 for my 5.1 system and it works great. Thanks man!!!
hello then for subwoofer ?
what amp did you use
TDA 2050 is not 5 channel ic. so how can you drive 5 speakers at a time.
we can use 5 tda2050 to drive 5 speakers
já montei vários circuitos que encontrei na internet, mas muitos não deram certo. os resistores não casavam bem com os circuito integrado que eles pediam.
TDA–>best choice for simple & cheap ampplifier.
on the TDA7294. Im confused with the Standby/mute. Is there a way i can completely remove this from the circuit? I have seen TDA7294 plans that remove pins number 5 , 10 and 11 (snapped off) with the standy was connected to the ground (from what i could tell) Would that work? I do not need these functions. PS: THANKS FOR THE PLANS =)
sir iam using tda7294 bridge amp circuit output is very good but input supply voltage range? Iam using 30-0-30v 5A transformer but IC very heat at the time output very very low please help me sir
input supply voltage range in tda7294 bridge amp circuit
After fighting some time with a 50W RMS amplifier, self-designed with TIP122 and TIP127 at the output stage, I decide then to implement an integrated cirtuit option. I chose the TDA2002 (similar to TDA2003) on bridge configuration. Feeding it with +21 volts and a 4 ohms load, can obtain over 30 W RMS at the output with good stability. An interesant option for domestic use.
TDA best choice for simple & cheap amplifier at home.
THANKSZ
Which type of capacitors are used in tda 2003 bridge amplifier 18watts
I think here some TDA boards are missing out I think TDA had a60 watt Amp board
nice…
good
Sir,
I want build a 200 watt subwoofer amp with TDA 7294 IC. Please sned me the circuit diagram with pcb lay out. Hoping with better response.
Thanks,

Hi all,
I need DATA sheet of Ic TDA15520.
I hope to get it as early,
Thanks,
