Audio Power Amplifier LM3886

Audio Power Amplifier LM3886
Audio Power Amplifier is an important part in the reproduction of sound in a sound system. Audio Power Amplifier LM 3886 with power IC Audio Power Amplifier is a highly capable and able to produce 68 Watts with power rata2 4Ohm load and capable of producing power 38 Watt with 8Ohm load. With good sound reproduction capabilities of 20Hz-20kHz is also included on this LM3886 Audio Power Amplifier. LM3886 Audio Power Amplifier is equipped with spike protection that will protect the output circuit from overvoltage, undervoltage, overloads, konrsleting power supply, thermal runawaydan peak temperature. Audio Power Amplifier LM3886 also features a noise reduction system which can keep the audio from the noise well.

1500W High Power Amplifier

Circuit Power Amplifier has a power output of up to 1500W RMS, power amplifier circuit is often used to power sound systems needed to outdor. In a series of images can be seen the final power amplifier uses 10 sets of large power transistors for the ending. This power amplifier circuit using a transistor amplifier starting from the front, signal splitter, driver and power amplifier. Current consumption required is quite large power amplifier that is 15-20 A for this 1500W power amplifier circuit. Supply voltage needed by the power amplifier in order to work optimally is symmetrical 130VDC (130VDC ground-+130 VDC). 1500W amplifier circuit below is a picture series of mono, if you want to create a stereo it is necessary to make 2 copies of the circuit. For more details can be viewed directly image following a series 1500W power amplifier.

Stereo Amplifier with Tube

Stereo amplifier is very simple, consisting of 5 active components including the power supply it. Series Stereo Amplifier With Tube was prepared with 5 units trioda tube consisting of 1 unit tubes 5Y3 GT vacuum rectifier, 2 tube tube trioda 6SF5 GT high-mu tube 6k6 and 2 units which form the power beam amplifiers. Power consumption for the circuit with a tube stereo amplifier is not more than 45 Watt. Current consumption for the circuit with a tube stereo amplifier is around 3A. A complete range of stereo amplifiers with this tube can be seen from the following series of images.

Tube amplifier with power 25 Watt

Tube Power Amplifier 35W Push Pull is made using a tube and eventually compiled configuration push-pull amplifier. Tube Power Amplifier 35W Push Pull tube til it using EL-34 as the amplifier end.

Low Cost Digital Volume Control Amplifier

TDA8551 Mini Digital Volume Control Amplifier
Amplifier with digital volume control can we create a predictably simple because the article Mini BTL Amplifier with Digital Volume Control This series is made ​​only with 1 IC TDA8551. The series of Mini BTL Amplifier with Digital Volume Control is a power amplifier with BTL type 1Watt. Techniques for adjusting the volume in this series has been provided with a pin point control that is controlled by providing an input voltage VCC and GND. The series of Mini BTL Amplifier with Digital Volume Control selector also features mute, standby and operating.

The series of Mini BTL Amplifier with Digital Volume Control is quite simple and small enough to make an amplifier for room or to headphones. Hopefully useful and can provide ideas for making digital amplifier with volume control.

Video Amplifier Circuits

Video amplifier circuit is simple and can be used. Video amplifier circuit was constructed from 2 pieces of transistors BC550 and BC560. The source voltage used for supplying the video amplifier circuit is 5VDC. Video amplifier circuit is equipped with a powerful regulator which flows through both transistors T1 and T2, the components used to manage these flows are P1 and P2. Then the video amplifier circuit is also equipped with limiting the maximum current that passes through T1 and T2. The components in black block functions as limiting the maximum current that is passed by the T1 and T2 for no more than 5mA.

High Impedance amplifier circuits

Mini High Impedance Amplifier is an amplifier with 1 Watt and have a very high input impedance. The series amplifiers can have a very high input impedance because the use of two transistors in the input that is placed Darlington. Input impedance circuit amplifier achieves 20M Ohm. Mini High Impedance Amplifier circuit uses four transistors and an IC 741. Gain amplifier with high input impedance , we can provide the input signal from device with weak levels though.

High Impedance amplifier circuits

Mini High impedance amplifier circuit is very cheap to make and quite simple. This amplifier circuit use 9VDC power supply.
