This is a series of 150-watt amplifier based bribge ic TDA 7294. for SIM connections have been removed and some signs of components have been displaced. 220UF 100nF Although I have shown how C1 3.3UF Electro bipolar, you can use the CAP polyester, if you want. If power will be used for serednochastotnyh or tweeters in the system biamped or triamped, C1 may be reduced by the cost 100nF (-3dB at 72Hz). For general use, you can use a 1uF polyester, giving-3dB frequency of 7.2Hz, but bass extension is better with a higher value

Skema Rangkain 150-Watt Bribge Amplifier TDA 7294

As you can see, there are provisions to use TDA7294 well. This circuit is almost identical, but a specification higher. There are links on the board to connect contacts 1 and 5 (it should not be connected to the TDA727). Use TDA7294, fees can run bridged (BTL or bridge tied load) to about 150 W at 8 ohms. I think P87B be used to provide phase signal is necessary for BTL operation. Although it is common to see AMP as a reversal, there is a very low resistance at first, and may lead to unacceptable pressures and possible distortion. P87B be managed separately by each amplifier, and the best way to control the amplifiers.While parallel operation is often recommended, I strongly recommend that you run the amps in parallel. There are very strict requirements for greater tolerance for parallel operation – usually amplifiers must correspond to 0.1% or more for all audio traffic and beyond. A very low output resistance of members, even inconsistencies 100mV (instantly, any voltage and frequency) can cause large amounts of current flowing through the circuits. Although 0.1Ω resistors are usually offered, inconsistencies 100mV voltage (0.15% at the peak voltage 60V) 0.5A cause a circulating current. This leads to overheating and protection of anger involved.

14watt Audio Amplifier TDA2030

TDA2030 amplifier circuit is a monolithic IC intended for use as a low frequency class AB amplifier. TDA2030 provides 14W output power (distorsions = 0.5%) at 14V/4Ω and at ± 14V or 28V is 12W/4Ω or 8W/8Ω. TheTDA2030 provides high output current and has very low harmonic and cross-over distortion which made it one of the most used IC in audio amplifiers designs.

The performance from this circuit is very satisfactory. The sheet contains data for typical noise and distortion statistics, I cannot confirm these statistics because I don't have the equipment, but my ears tell me that the sound is good and with sensitive speakers, this amp will show some power. As can be seen, the circuit is quite simple indeed. If you can make your own PCB he circuit is very simple to make and you can design the PCB to accept the odd, staggered pin-outs of some TO220 devices.

Skema Rankaian 14watt Audio Amplifier TDA2030

PCB layout TDA2030

Resistors should be at least 1/4W types with 1% tolerance recommended. I used 0.6W 1% metal film resistors and they work well. Capacitors I used were electrolytic cans for C2, C5 and C6. At the time of building, I did not have enough 100uF caps so I used 220uF caps instead, this will not cause trouble, unless you use caps that are smaller than 100uF for C5 and C6.

C1 can be electrolytic, I used a tantalum myself (don't ask why, since they are actually more expensive). Some readers may want to use a polyester capacitor for the input (C1), this would work too but I am not sure whether any benefit will arise from the extra expense. Other capacitors (bypass caps C3 and C4. and C7) are ideally polyester caps. Mylar may be used but I prefer polyester caps and they are not expensive unless you get large values.

The values of R5 and C8 are worked out from the equations in the datasheet, but I used 1.8k ohm for R5 and 220pF for C8 and they work fine. Diodes should be 1N4001 or similar (make sure you solder them in the right way round).

A good heatsink is important and this should be a large size with good thermal conductivity. When you operate the TDA2030 from the (recommended) split rail power supply, you must insulate the device from the heatsink using a mica washer or similar. With single rail supply, this is not needed.

There is a circuit uses a high quality audio amplifier IC TDA2050. The power amplifier can provide 32 watt rms into 4ohm load and 25 watt rms into 8ohm. The circuit features low harmonic and crossover distortion and a low external component count.

Skema rangkaian TDA2050 Power Amplifier

Voltage gain is 27dB as shown, but this can be changed by using a different value resistor for the feedback path (R4, currently 22k, between pins 2 and 4). The amplifier must not be operated at any gain less than 10 (20dB) as set by R4 and R5, as it will oscillate. In some cases, an inductor may be needed in series with the output to prevent instability with capacitive loads (10 turns of 0.5mm wire wound around a 10 Ohm 1W resistor). The most common capacitive load is the speaker cable itself, and 'audiophile' leads are often worse than standard grade cables in this respect.

The 1 Ohm resistor (R6) should be a 1W or 0.5W type, and all others should be 1/4W 1% metal film (as I always recommend). All electrolytic capacitors should be rated at 50V if at all possible, and the 100nF (0.1uF) caps for the supplies should be as close as possible to the IC to prevent oscillation. C1 should be a bipolar (non-polarised) electrolytic, or may be plastic film if you prefer.

The supply voltage should be about ±25 Volts at full load, which will let this little guy provide a maximum of 25 Watts (rated minimum output at 25°C). To enable maximum power, it is important to get the lowest possible case to heatsink thermal resistance. This will be achieved by mounting with no insulating mica washer, but be warned that the heatsink will be at the -ve supply voltage and will have to be insulated from the chassis.
