Amplifier circuits with TDA7294, LM3886, TDA2030, LM1875 and many different models. Integrated amplifier circuits are easier to construct than transistor amplifiers, and high-power amplifiers can be built with fewer electronic components.

TDA2005 Amplifier Circuit

| 2024/03/16

TDA2005 is a classic integrated circuit that achieves great things with low voltage. You can use it as a stereo or bridge depending on its location. It does not hesitate to protect itself in high temperatures and short circuit situations. In this study, we did a sweaty bridge connection study with him. Although it is…

Tone Controlled Stereo Amplifier

| 2023/03/19

Tone controlled stereo amplifier circuit. You can use TDA7377 or TDA7374 amplifier IC. LM1035 or LM1036 IC can be used for tone and volume control. The cooling fan control made using TL081 op amp contributes to the circuit. Has adjustable voltage output with LM317 to power mp3 player or other audio sources.. The LM1035 (LM1036)…

High Quality Amplifier Circuit LM3886

| 2021/09/30

The dimensions of the PCB board are 80×80 mm. Each board is equipped with its own protection device that disconnects the load in emergency situation (appearance of constant voltage at the output or breakage of any of secondary windings of the power transformer), as well as performing the necessary load connection delay when power is…

The whole is designed as a small module with dimensions of 30mm × 38mm, which “will fit anywhere”. The TDA1517 amplifier module can be used in self-made sound equipment or mounted in…

STK442-090 Amplifier Circuit

| 2019/08/08

The proposed STK442-090 amplifier circuit is a compromise, because STK442-090 is a microassembly, it is also a hybrid integrated circuit (GIS). What it is? Take an excerpt from Wikipedia: “microassembly is an integrated circuit in which, along with elements that are inextricably connected on the surface or in the volume of the substrate, mounted micro-miniature…

20W Stereo Amplifier With TDA2003 Tone Control

| 2019/06/14

Many times we have been asked about an amplifier that can be powered with the computer source to amplify this. We have also seen the need for an amplifier that can be transportable everywhere and that provides an acceptable power service. Thinking about filling these expectations, we present a 20W stereo amplifier (10W per channel)…
