But on single supply setting.. Circuit diagram of 35 watts amplifier using TDA Typos in my previous comment: Also below is an updated list of components for the new PCB. However, in the foregoing, there are various suggestions regarding enhancing its output power. First of all, we look at the circuit diagram below. Audio-Mist 4 May Reply.

That is not even as good as the TDA Each power supply rail has a 10,uF capacitor which is shared between the channels. Have fun building this one!

Dr Tim datasgeet Jul Reply. Have fun building this one! A double pole, double throw DPDT switch is shared between both channels and this allows switching the output between speakers output or headphone output.
The PCB layout must be mirorred to expose the copper. A torroidal transformer with dual 18 Volt secondaries and rated at VA 3. It produced bzzzz sound.

Flip the exposure film to the left. The complete PSU project should explain itself. Isolate the 2 pcs power transistor only. I used a protoboard for my amplifier details below. It produced bzzzz sound. For the heat sinks I used a pair that each measured 50 mm x 88 mm with 35 mm fins and rated at 2.
The speaker output plugs are standard three-way binding posts that will accept a 4 mm banana plug, a spade connector or bare wire. Please refer to your local electrical code for the mains connection requirements.
I have made a PCB design for the amplifier circuit. One thing to note is that the gain of the circuit needs to be at least tda datasheet to maintain stability. Ouassama thedjfreeman 6 Jul Reply.
TDA2050 Datasheet
This are knockoff parts not real TDA Short the output and they will go poof. D The diagram for single supply ; https: That is not even as good as the TDA Figure 2 the 25V CT V power supply of this projects.
The circuit has been constructed on a protoboard perfboard and the general layout follows the PCB design shown in Figure 2. Flip the exposure film to the left. Panggak 2 Mar Reply. Figure 1 below is from the data sheet and shows the pdt application using a split supply. Please refer to your local electrical code for the mains connection requirements.
One thing to note is that the gain of the circuit needs to be at least 24dB to maintain stability.
For the rectifiers I used 35A rectifier bridges A bridges should also work. The amplifier was built to drive a pair of my friends Klipsch RB Bookshelf speakers. The speakers are 8 ohms and have a sensitivity of 92dB 2.
Brother where you used Q1,Q2,Q3 and Q4?
I have made a PCB design for the amplifier circuit. The gain of the circuit is 33 dataxheet dB which should work well for most line level sources. If you do build one, Tda datasheet would be happy to see some photos of your TDA amps. This project requires a mains wiring connection or V which you do not want to get in between.
