Rangkaian Op-amp Headphone Amplifier RC-4560
Rangkaian USB Sound Card PCM2702
PCM2702 kebutuhan suku cadang tambahan hanya sedikit bekerja. Skema tidak kompleks. Kartu suara dapat diaktifkan langsung dari USB port (jumper W1) atau dari catu daya eksternal (jumper W3). PCM2702 membutuhkan dua power supply 3.3V (3V-3.6V) dan 5V (4.5V-5.5V). Saya menggunakan tegangan output tetap LDO TPS76733Q untuk 3.3V (IO2) dan output tegangan disesuaikan LDO TPS76701Q untuk 5V (IO3). Kedua LDO diproduksi oleh TI, saya menggunakan ini karena saya telah di laci saya. Setiap LDO serupa dapat digunakan. Tegangan output IO3 harus ditetapkan untuk sedikit lebih rendah dari tegangan input untuk memungkinkan stabilisasi LDO baik, dalam kasus saya adalah tegangan output diatur ke 4.8V. Tegangan output dapat diatur oleh resistor R33 disesuaikan. Dalam hal pasokan daya rendah, IO3 dapat disingkat oleh jumper W3. LED D3 signalizes daya.

Rangkaian Mosfet Amplifier
"BELAJAR ELEKTRONIKA - ASYIK" - Rangkaian Mosfet Amplifier. These amplifiers circuit can be used for virtually any application that requires high performance, low use Noise, distortion and excellent sound quality. Examples would be subwoofer amplifier should FOH stage Amplifiers, surround a canal a very powerful sound amplifier, etc. The 400W MOSFET-amplifier has four key stages of amplification. We are looking to start any Phase appropriate detail.
Di bawah ini adalah gambar rangkaian mosfet amplifier.
Di bawah ini adalah gambar rangkaian mosfet amplifier.
Gambar Skema Rangkaian MOSFET Amplifier
Note:
- Use + /-70V 10A DC dual supply for powering the circuit.
- For L1 make 12turns of enameled copper wire on a 1cm him: plastic formers.
- use 8 x IRFP448 MOSFETs in the final stages
- Heat sink is Necessary for the MOSFETs. A 8x4x4 inch finned aluminum heat sink will do. There is no such thing as a heat sink That is too large.
As the name suggests All Q ,C and ZD the Bias and buffer phases. Its main goal is to provide a stable MOSFET Gates and offset voltage and the voltage buffer amplifier stage of the High Resource capacity. What would have without the phase response and the effect Slew rate is indeed very bad. The flip side of the coin is not the extra step Introduction of an additional dominant pole in the amplifier feedback loop.
Also to what the name suggests this stage converts the voltage developed in the VAS and provides all the amps required to drive at 8 or 4 ohms. 2-ohm loads are possible for several minutes at a time. In fact, I have tested more than 1600 1kW amplifier Watts RMS at 2 ohms. But that would not be recommended as a long-term exposure at all. If it is higher than the figures of the STI-amp. Power to the AV amplifier 800 The components of the power for this amplifier are as follows, and are favored A channel or a power module alone. 1 toroidal transformer with a rating of 1kVA. Primary windings are made to fit.
Demikian bahasan kita kali ini tentang Rangkaian Mosfet Amplifier. Selamat mencoba dan semoga berhasil.

Rangkaian Power Amplifier DENGAN 2N3055. Daya Amplifier Circuit dengan 2N3055. Sederhana dan biaya rendah power amplifier. Akumulasi tegangan yang optimal adalah sekitar 50V, tapi ini tugas amp dari 30 sampai 60V. Tegangan menganggap akut adalah sekitar 0,8 - 1V. Seperti yang dapat Anda lihat, dalam arsitektur ini aparat menerima toleransi besar, sehingga Anda dapat tubuh itu tentang komponen, yang Anda akuisisi di rumah. Dan transistor NPN dapat setiap transistor tanda kemampuan, tetapi tidak menggunakan jenis Darlington. Kemampuan prestasi adalah sekitar 60 Watt.
Di bawah ini ANDA Bisa lihat gambar Rangkaian penguat daya DENGAN 2N3055.
Descriptions:
- capacitor C1 regulates the low frequencies (bass), as the capacitance grows, the low frequncies are accepting louder.
- capacitor C2 regulates the college frequencies (treble), as the capacitance grows, the college frequencies are accepting quiter.
- this is a chic B amplifier, this means, that a accepted charge breeze through the end transistors, alike if there is no arresting on the input. This accepted can be adapted with the 500? trimmer resistor. As this accepted incrases, the complete of the amplifier gets better, but the end transistors are added heating. But if this accepted decrases, the transistors are not heating so much, but the complete gets worse.
Semoga tulisan ini bermanfaat bagi Anda, hobbyist dan praktisi elektronika. Selamat mencoba dan semoga berhasil.

RANGKAIAN AMPLIFIER GITAR 100W
Rangkaian Guitar Power Supply
Rangkaian Guitar Pre-Amp
Guitar Power Amplifier
Guitar amplifiers are always an interesting challenge. The tone controls, gain and overload characteristics are very individual, and the ideal combination varies from one guitarist to the next, and from one guitar to the next. There is no amp that satisfies everyone's requirements, and this offering is not expected to be an exception.
One major difference however, is that if you build it yourself, you can modify things to suit your own needs, experimentation is the key to this circuit, which is presented in basic form, with every expectation that builders will modify just about everything.
The amp is rated at 100W into a 4 Ohms load, as this is typical of a "combo" type amp with two 8 Ohm speakers in parallel. Alternatively, you can run the amp into a "quad" box (4 x 8 Ohm speakers in series parallel - see Figure 5) and will get about 60 Watts. For the really adventurous, 2 quad boxes and the amp head will provide 100W, but will be much louder than the twin. This is a common combination for guitarists, but it does make it hard for the sound guy to bring everything else up to the same level.
Skema Mikrokontroler at89s51 Jam Digital
A digital clock is 1 that displays time digitally. The circuit explained here displays time with two ‘minutes’ digits and two ‘seconds’ digits on four seven segment displays. The seven segment and switches are interfaced with 8051 microcontroller AT89C51. This circuit may be used in vehicles, houses, offices and many others. The moment the Vcc supply is supplied to this circuit, the clock begins from 00:00. Time is displayed on four 7 segments (in frequent anode configuration) by utilizing the notion of multiplexing. That is reached by utilizing timer interrupt (Timer0) of AT89C51 which is configured to refresh 7 segments. The segments are refreshed numerous periods in the 2nd for simultaneous show. The clock runs which has a delay of precisely a single 2nd. Timer1 is used to produce a time delay of a single second. The info pins (a-h) of the many segments are interconnected and get signal from port P2 in the microcontroller. The control or allow pins (popular anode) are connected to pins 1-4 of port P1 (P1^0 - P1^3).
The number on 4th section (displaying the unit digit of 2nd) is incremented as soon as in the 2nd since it goes from 0 to nine. The range on 3rd section is incremented just after every 10 seconds from 0 to 5. Hence seconds are displayed different from 00 to 59. The digit to the 2nd section variations after every 60 seconds (a minute) from 0 to nine etc. So the clock runs for an hour and following that it resets to zero once more
