The TDA2030 Bridge amplifier can be used with a single source power supply. Working voltage DC 12V…. It is between 32V and can be operated with 12V battery, 24V battery, SMPS adapters or transformer power supply. (power of the voltage source according to the output power is 50W…60W) The principle of the TDA2030 Bridge connection…
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 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)…
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…
A full-fledged stereo power amplifier with the TDA1517 chip. It is powered by single voltage, achieves 2×6W output power at 4 Ω load. 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…
HI-FI 2 x 80W Power Amplifier on STK442-090 Micro assembly Most radio amateurs can be divided into two categories: supporters and opponents of microcircuit amplifiers. As arguments for using such amplifiers, the former cite the simplicity of the circuit, high reliability and stability of operation due to the high integration of the microcircuit. As a…
The core of the whole amplifier circuit is the TAS5630B one connection is based on modified the recommended BTL mode stereo input, which is listed by the manufacturer in Selection of the final chip involvement consisted of four different modes, of the optional input pins M1 to M3: TAS5630B 2 x BTL – two separate…
The module is based on the popular LM4766 chip, completed with a symmetrical power supply. The assembled plate is a ready-made functional block of the audio system. The circuit diagram is shown in circuit schematic. The U1 (LM4766) systems operate in a non-inverting configuration. The input signal from the IN socket, through the C5 and…
PC sound cards with multiple line outputs are commonplace than left and right channel for classical stereo reproduction. The described TDA2040 amplifier is designed especially for sound cards with four 2 + 1 + 1 output channels even those who have only a standard stereo signal, the amplifier described is complemented by simple custom ones…
Small amplifier TDA7377 of 15W + 15W + 30W in 4 ohms At the request of our followers, we have developed an amplifier with the following characteristics: The TDA7377 is the main component. It has 4 outputs that can deliver a power of 15W each. we distribute them as follows: First, we have 2 outputs…
