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…
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)…
The amplifier uses a hybrid two-channel IC STK4241-II manufactured by SANYO. Immediately, it is worth noting that the pinout of the STK4241 is compatible with such chips as the STK4201V-series (THD = 0.08%) and the STK4141-series (THD = 0.02%). In the archive for download you will find 5 technical descriptions (DATASHEET) on STK4201, STK4211, STK4221,…
The output transistors MJL21194 are of great power and performance. They must be very well adjusted with through screws, washers and nuts and properly insulated from the heatsink with mica insulators. Remember to use silicone grease and tighten the screws very well, so that the heat is transmitted from the transistors to the heatsink. After…
Making an Amplifier is sometimes very challenging in the Amplifier. It is important for us to use easy-to-process material for the amplifier box, because the indicator, fan and so on. In order to have a fine workmanship for the sections, there is usually no equipment and materials suitable for these jobs in the amateur workshop.…
Previously shared RMS 250W auto amplifier JBL filter SMPS EI35 SG3525 project is similar to the PCB design is a very regular auto amplifier circuit. You can use 2x100w rms stereo or 200w rms mono, which can be controlled by bridge connection as well as bass control with cross over circuit with adjustable TL072P op…
The edited versions of the Holy Holton AVXXX series amplifier circuits are of high quality PCB designs. The power transistors of the 400W Amplifier circuit are BJT 2SC5200, 2SA1943, or Mosfet IRFP240, IRFP9240 can be used for this and will change materials for use. Supply voltage symmetrical + -80V DC pcb, schematic, material list etc.…
