STK4172-2 power amplifier IC gives you a very low-noise ratio THD stereo 2x40w = 0.4% max supply voltage symmetrical 2x48v dc recommended value 8 ohm speaker with amplifier is feeding on a solid addition to the same pcb with passive tone, voice control circuit. STK4172II AF Power Amplifier • Small-sized package whose pin assignment is…
I have seen a site similar to the classic, but darlington transistor-quality hifi amplifier circuit. very few elements with the less clean up audio element that account. the beautiful thing about all the details, there is a list of the schema, pcb, set of illustrated information on the flow of material, calm, etc.. 100W amplifier…
DX Blame Series Amplifier circuits BJT Transistors based on quality design .. I had never heard the name before, but became popular on YouTube pretty abroad “DX Blame” video had a lot of practice if you search on. There DX Series 4 mohel ES Blame, Blame MKII DX, DX Blame MKII Supercharged DX Blame ST…
A complete amplifier module for subwoofer on the TDA7294 bridge. Implemented functions: power amplifier based on TDA7294 (70-140W) gain regulation adjustable low-pass filter (80-150Hz) with the option of shutdown (full-band operation) phase switch (0-180 degrees) subsonic filter (passive 3-order 19,25,33 Hz to choose from) auto-on / off with the switch of this function (ON /…
I also post a car amplifier, 100% own achievement. The amplifier consists of SMPS (switching source), SG3525 oscillator and 4 + 4 N-mos IRFZ48 and the amplifier is according to the “classic” N-mos 350 scheme with 6 IRFP240 endpoints. The transformer for SMPS is made of two smaller transformers recovered from an inverter, of which…
TDA1514 stereo previously had shared 2 × 50 amp circuit, see: TDA1514A high performance HiFi 2X50W amp circuit This circuit can be used for single-channel 50w output printed circuit sizes quite small and symmetrical placement of smooth supply voltage can be between 2 × 10 volts, 30 volts 2x material list diagram, PCB drawings are…
Headphone Amplifier Circuit simply have a design or even the first single MOSFET as the design begins after two MOSFETs used and 6n6p ecc99 lamp Adding the lamp operating voltage 70 … 80V inter-addition for the MOSFETs 18 … 20v voltages required. The second box of the amplifier are also very well designed. Hybrid schemes…
I think there is no one who knows the 200w amplifier circuit, whose power is increased by connecting 2 TDA2030 power transistors to its outputs. I first saw this circuit in the elektor in the 2000s. There was a thin and long PCB printed circuit drawing. It worked very well. Actually, my purpose in making…
Apex B500 power amp’s pcb design stylish been output mje15032 and mje1503 power transistors used supply voltage symmetrical 55v … 90V from quite high dangerous circuit tests, be careful addition amphitheater to be used with fan control and protection circuit diagrams and PCB drawing is on.
