I used a protoboard for my amplifier (details below). This circuit must use a good power supply so that the sound quality could be as expected. enter your email address and we'll send you a link to reset your password. One dual secondary (2 x 18VAC / about 160VA) is your friend. Try keep the signal wiring as short as possible. If a short-circuit or an overload dangerous for the final transistors are detected, the concerned SOA circuit sends out a signal to the latching circuit (with a 10µs delay time that prevents fast random spikes from inadvertently shutting the amplifier off) which makes Q1 and Q2 saturate (see Block Diagram). 14 Typical amplifier with split power supply Fig. For the input DC blocking capacitor I used a 1uF Audyn MKP (metalized polypropylene film) capacitor. You will also want to keep them away from any AC sources like the mains power cord and the transformer. A schematic of the amplifier I built is shown below (Figure 3). Wiring information: Use a transformer as suggested on the project page. 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 or 8W on a 8Ω. A torroidal transformer with dual 18 Volt secondaries and rated at 120VA (3.3A per secondary) is used. If you are looking for the best audio amplifier circuit. Most film type capacitors (polypropylene, polyester, mylar ...) should be a large improvement over electrolytic caps which I don't recommended. The headphone adapter is from the Rod Elliott (ESP) site which you can reference for more details. 32W Hi-Fi AUDIO POWER AMPLIFIER, TDA2050 datasheet, TDA2050 circuit, TDA2050 data sheet : STMICROELECTRONICS, alldatasheet, datasheet, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes, triacs, and other semiconductors. when compared with cost wise the ic having 20- 70 rupees ( 1$ ) only. Ground The amplifier is designed to operate with a minimum • Thermal Protection with Parole Circuit of external components. By going through the datasheet, I have found that the TDA2050 can output 28 Watts into 4Ω speakers with 0.5% distortion on a 22V power supply. It's a no brainer - also for beginners. I have made a PCB design for the amplifier circuit. Additional details to determine an appropriate size of heat sink are described in the data sheet. If you do not need a headphone output, you can eliminate the DPDT switch and the resistors after the switch. we should use the 25v ct The PCB layout for the power supply can be used with standard copper clad board or photo PCB. We can alter the circuit diagram then we will get up to 50 watts output. Note that the input jacks and speaker binding posts are insulated from the chassis using the supplied nylon spacers. The amplifier is built around a single integrated circuit (IC), the TDA2050V which is produced by STMicroelectronics. The data sheet also includes a PCB design (shown in Figure 2) that one can use. The circuit has been constructed on a protoboard (perfboard) and the general layout follows the PCB design shown in Figure 2.
