March 3rd, 2008 TDA2005 2×20 Watt Stereo Amplifier
TDA2005 2×20 Watt Stereo Amplifier description:
This circuit is a small stereo amplifier for all suitable applications like amplifying small speakers, boxing, etc. It is also suitable for car use but before, the power supply must be choked with at least 150mH and it must give up to approximately 6 to 7 amps during the upstream performance.
Appropriate heatsink for the amplifier is SK08 with a height of 50 mm (approx. 2.5 K per watt). You should drill the cooler after soldering the board to center it properly. The TDA2005 also needs not be isolated from the heat sink, since the metal mounting part of the IC is grounded. You should use thermal paste to improve the heat dissipation. After the assembly , case construction is left to the builder. 100K potentiometers are used for adjusting the input volume. The potentiometers are absent in the layout. The 100K resistors need only be installed if the 100 K potentiometers are not used as shown in the layout. For full info on TDA2005 2×20 Watt Stereo Amplifier visit project page.

It’s not typical aplication of TDA2005. Please let me know if anybody tested this amp.
Thank You

greg that is typical aplication, and as you can see from the picture it has been build and tested but not by me, so i can’t provide any details

very very good

Alfredo R goes for Ohms, You’ll find it very common in schematics posted on the internet or in books. So if you’ll see 1.0 R it means 1.0 Ohms or 1R5 means 1,5 Ohms. Same rule applies for K or M which mean Kilo-ohms and Mega-ohms. I hope you got the idea

El circuito a sido probado?
Estan seguros que funciona?
La entrada de audio es por cable RCA?

Trix, the circuit has been made as you can see from the picture, The Input can be any type of connector that you like. and if you have more questions, please post them in english

hey man.. what’s up with the 100k resistors?? they can be replace by the 100k pot? sorry by my english.. the pots control the volume for each chanel??

can somebody post the part’s list of TDA2005 2×20 Watt Stereo Amplifier for me please… or email me @ climor_cyut [at] yahoo.com tnx a lot..
and please send me stereo type amplifiers any wattage will do tnx again..

froi, see the data sheet tda2005 ,but if you need these one after the text is the link (TDA2005 2×20 Watt Stereo Amplifier: [Via] - [schematic, PCB and layout files])

I thought that this circuit is already dead technologically
Why not try to make amplifiers with circuits less technologically, which are specially designed to operate in the bridge mode at somewhat higher powers at a much lower THD, for example :
TDA8220, TDA8221, TDA8231, TDA8233, TDA8560
And pure specialized circuits for automotive power amplifiers:
TA8251, TA8254, TA8255, TDA8569
And for very high power:
TB2901, TB2902, TB2903, TB2904, TB2906, TDA1562

but after i downloaded (TDA2005 2×20 Watt Stereo Amplifier: [Via] - [schematic, PCB and layout files]) there is no part’s list included =c
please help me, i dont know the names of other materials in TDA2005 ste-amp..specifically that color yellow and color grey and the value of capacitors =c

i also tried tda2005 data sheet but there is no exact answers =c
