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…
Mono power module, based on LM3886 application. He enjoys very high popularity and good reputation even among audiophiles who are “overly sensitive to everything that is integrated”. The LM3886 integrated circuit is based on bipolar transistors. It is equipped with protection circuitry for overheating, overload, and a very useful muting circuit for switching on and…
Amplifier 4×60 Watts. To its solution was first selected integrated circuit LM3886T. The proposal continued the calculations and the election of the additional components of the integrated circuit and the design of printed circuit connections. To the end amplifier was also designed system of active cooling. In the fourth chapter was made the proposal of…
LM3886 Amplifier integrated is very popular, many applications have been made, I made a special design and I am sharing it. First of all, there are differences between the photos and the pcb, some because of the material values I have and some because they are in the development phase. You should take the PCB…
This car amp circuit one where I saw the original, but only there was a picture I think he of the amplifier clone anyway .. circuit of the amplifier on the floor 2 LM3886 is used used in car 12v battery voltage symmetric 2 × 40 volts to turn sg3525 based on the DC to…
I used to implement a rampant LM3886 application BPA300 LM3886 notes will take a lot of time, but I couldn’t find the çizmeside circuit was just a search, I found the drawing but the pcb is double trouble. If you want to make, single-layer pcb design, symmetrical supply circuit, the input amplifier, 220v with soft…
Always on my mind I would say if you did a nice 2.1 amp circuit .. although oddly fond of side projects on the internet, not a nice mono, stereo amplifier circuit as they do not have in abundance , but 2 +1 … Half- bass is solid at National Semiconductor LM3886 amplifier integrated product…
Stereo auto amp project amplifier 2 for LM3886 for supply sg3525 used the converter input voltage 12v … 14.4 v between output and 2 × 30 volt transformer for the FT140/77 toroidal ring core (inner diameter of 0.9 outer diameter 1.4) used PROM winding three 1mm wire 2 × 5 connected in parallel to the…
Previously normal for LM3886 and TDA7294, for bridge connections but this feature of the project was shared circuits designed to bridge the connection of PCB layout drawings and small size of the smooth double-sided construction drawings to be as bad a little difficult My first attempt at a double-sided PCBs had a bit lot of…
LM3886TF Amplifier circuit pretty a quality PCB design has to supply the diode bridge and filter on the capacity also for the volume control stereo 100k potentiometer attached LM3886 inputs and outputs used in this opamp NE5532 instead ad827 used opamp beslemesiç the same pcb on the 7815 and 7915 fixed regulator IC supply with…
