AMPLIFIER ON TDA7388

Philips' latest development in the field of integrated UMZCH is called TDA7388 and provides maximum power of 40 watts for each of the four channels. The microcircuit is made in a standard 25-pin package. Judging by the datasheet, the amplifier provides low level noise and nonlinear distortion. See microcircuits for details.

The TDA7388 amplifier has protection for the output stage from short circuit and overcurrent, power reversal and thermal protection. When pin 4 (st-by) is disconnected from the positive of the power supply, the microcircuit is switched to standby mode with low current consumption, and pin 22 is intended to mute the sound.

Audio amplifier circuit on TDA7388

Specifications amplifier on TDA7388:

• Supply voltage: 10-18 V
• Frequency band: 20-20000 kHz
• Input voltage: 0.05V
• Load impedance: 4 ohms
• output power 4x40 W
• Harmonic distortion: 0.15%

When operating this ULF, it should be taken into account that a power of 40 watts per channel will only be obtained with a maximum power supply of 18 V and a Kni level of about 10%. For comfortable listening with Kni down to 0.1%, the power must be reduced to 10-15 watts, which is also not bad, because the total power will still be more than 50 watts. I think this will be quite enough for any room and car interior.

The amplifier microcircuit itself is mounted on an aluminum radiator with an area of ​​50 square cm and all that is required of you is to correctly solder the wires to the contacts of the microcircuit. To obtain maximum power, it is better to power the microcircuit not with standard 14 V, but with 18 volts increased to the maximum rating value. Don't be afraid to burn it - the protection won't let you. If you have problems finding a suitable transformer or power supply, use an ATX power supply for this, as done in

Hello dear friends! Today we will look at the assembly of an amplifier based on the TDA7386 chip. This microcircuit is a four-channel low-frequency amplifier of class AB, with a maximum output power of 45W per channel, into a 4-ohm load.
The TDA7386 is designed to increase the power of car radios, car radios, and can be used as a home amplifier, as well as for holding any indoor parties or outdoor events.
The amplifier circuit on the TDA7386, in my opinion, is the simplest; any beginner can assemble it, either by surface mounting or on a printed circuit board. Another wonderful advantage of an amplifier assembled according to this circuit is its very small dimensions.
The TDA7386 chip has protection against short circuits on the output channels and protection against overheating of the crystal.

You can download the datasheet for this chip at the very bottom of the article.

Main characteristics of TDA7386:

• Supply voltage from 6 to 18 Volts
• Peak output current 4.5-5A
• Output power at 4 Ohm 10% THD 24W
• Output power at 4 Ohm 0.8% THD 18W
• Maximum output power at 4 Ohm load 45 W
• Gain 26dB
• Load resistance not less than 4 Ohm
• Crystal temperature 150 degrees Celsius
• Reproducible frequency range 20-20000 Hz.

The amplifier can be assembled according to two schemes, the first:

Component ratings:

C1, C2, C3, C4, C8 – 0.1 µF

C5 – 0.47 µF

C6 – 47uF 25V

C7 – 2200uF and more than 25V

C9, C10 – 1 µF

R1 – 10kOhm 0.25W

R2 – 47kOhm 0.25W.

Component ratings:

C1, C6, C7, C8, C9, C10 – 0.1 µF

C2, C3, C4, C5 – 470pF

C11 - 2200uF and more than 25V

C12, C13, C14 – 0.47 µF

C15 – 47uF 25V

R1,R2,R3,R4 – 1kOhm 0.25W

R5 – 10kOhm 0.25W

R6 – 47kOhm 0.25W.

The only difference is in the wiring of the microcircuit, but the principle does not change.

We will assemble according to the first scheme, if anyone is interested in the second scheme, you can read the article: “”, the second scheme is discussed in detail there and printed circuit board To her. The TDA7386 and TDA7560 microcircuits are identical in pinout and interchangeable. One main difference is that the TDA7560 is designed for a 2 Ohm load, unlike the TDA7386, the rest of the parameters and characteristics are similar.

You can download the printed circuit board below the article.

The radiator must be installed at least 400 square centimeters. In the photo below, you can see the TDA7386 amplifier I assembled with a radiator with an area of ​​less than 200 square centimeters. I tested this amplifier for several hours, the load included two 30W speakers with a load of 8 Ohms each, at an average volume level, the microcircuit got very hot, but no problems were noticed. This was a test, I advise you friends to install a radiator of at least 400 square centimeters or use the amplifier case as a radiator if it is aluminum or duralumin.

The radiator must be cleaned with fine sandpaper at the point of contact with the microcircuit; if it is painted, this will increase thermal conductivity. Next, place it on a heat-conducting paste, such as KPT-8.

Details.

The capacitors can be ceramic, you won’t hear the difference if you install film. Resistors with a power of 0.25 W.

A little about the ST-BY and MUTE modes on the TDA7386 chip (pin 4 and pin 22).

The ST-BY mode on the TDA7386, as well as on its brothers (TDA7560, TDA7388), is controlled as follows; if you want your amplifier to be constantly in the “On” mode, then you need to connect the outermost terminal of the resistor R1 to + 12V and leave it in this position, that is, solder a jumper. If the jumper is removed (the outermost terminal of resistor R1 is left in the air), then the microcircuit is in standby mode; in order for the amplifier to start singing, you need to briefly connect the outermost terminal of resistor R1 to +12V. In order to put the amplifier back into standby mode, it is necessary to briefly connect the extreme terminal of resistor R1 to the common negative (GND).

The MUTE mode on the TDA7386 is controlled in a similar way. In order for the amplifier to be constantly in the “Sound on” mode, it is necessary to connect the outermost terminal of resistor R2 to +12V. If you want the amplifier to operate in the “Silent” mode, then you need to connect the outermost terminal of resistor R2 and hold it with a common negative (GND).

I assembled several amplifiers on TDA7560, TDA7386, TDA7388, I noticed one thing, if you leave R1 and R2 in the air, while using only one input out of four, then when power is applied to the board, the amplifier is in standby mode, all of the above operations are with ST modes -BY and MUTE work fine. If you use all the inputs, then when power is supplied to the board, the amplifier itself begins to sing, although power is not supplied to legs 4 and 22. However, experiment!

The article presents a project to create an amplifier on a single chip TDA7297 a simple powerful stereo amplifier 2 x 15 W powered by 12 volts. It has a minimum of parts and is very compact just like .

Building an amplifier on the TDA7297 chip does not require much kit. Electronic circuit built according to the scheme proposed by the manufacturer from the datasheet with minor modifications. In particular, a modification to the typical TDA7297 amplifier circuit is to add a volume control using a 10 kOhm dual logarithmic potentiometer.

TDA7297 - connection diagram from datasheet

This diagram from the datasheet shows how easy it is to connect the TDA7297.

TDA7297 - power amplifier circuit

Below is a diagram of an amplifier based on the TDA7297, which you can assemble yourself. The TDA7297 amplifier is an output bridge chip and, therefore, the connected speakers must be equipped with electrolytic capacitors.

The configuration of the output bridge is simple - two identical amplifiers for each channel, operating in antiphase. Each output pin is connected to one pole of the speaker. This output voltage control allows high power to be achieved with very low supply voltage. According to the declared parameters of the TDA7297 chip, this circuit can operate at voltages from 6.5 volts to 18 volts. IN this option a voltage of 12V was used.

A resistive divider consisting of two 47 kOhm resistances and an electrolytic capacitor of 10 uF at 25 volts are used to eliminate distortion when turning on the power. Two 2.2 µF capacitors - polyester or ceramic.

Microcircuit pinout

Chip TDA7384 It is actively used in car radios and provides very good sound. Inside the microcircuit there is a standard transistor amplifier, the output stages of which operate in AB mode, so the sound quality is quite high quality as long as the rated voltage of the input signal is exceeded. This voltage should not exceed 3 volts, taken from the pre-amplifier of the car radio. By the way, microcircuits TDA7384, TDA7386, TDA7385, TDA7383, TDA7381 They have the same connection diagram and differ only in output power.

On some forums you can read negative reviews about the microcircuit, in particular that the microcircuit has poor performance, gets very hot, the sound is choppy, there is a lot of wheezing and noise. I personally have made many amplifiers on this microcircuit and have not noticed anything like this, you just need to be able to handle microcircuits of this kind correctly.

During soldering, place the microcircuit on the heat sink; this will prevent it from overheating and also saves it from static effects. An important point The filtration part is that the further operation of the amplifier depends on the correct power supply filter.

Throttle- designed to partially suppress high-frequency network interference. Unfortunately, we will not be able to completely suppress HF noise with at least one choke, so sometimes two chokes are used. Take electrolytic capacitors with a large capacity, they play important role to stabilize voltage and suppress low-frequency interference.

Chip TDA7384 has Standby and Mute modes (sleep and mute modes, respectively). The amplifier also has a Rem function.

Input wires should be used shielded, this will not sound signal deteriorate before entering the microcircuit. In this case, the installation is performed on a circuit board made using .

Currently, a wide range of imported integrated low-frequency amplifiers has become available. Their advantages are satisfactory electrical parameters, the ability to select microcircuits with a given output power and supply voltage, stereophonic or quadraphonic design with the possibility of bridge connection.
To manufacture a structure based on an integral ULF, a minimum of attached parts is required. The use of known-good components ensures high repeatability and, as a rule, no additional tuning is required.
The given typical switching circuits and main parameters of integrated ULFs are designed to facilitate the orientation and selection of the most suitable microcircuit.
For quadraphonic ULFs, the parameters in bridged stereo are not specified.
