Hi-Fi AUDIO POWER AMPLIFIERS

Small stereo amplifier project for computer

you want will build a Small stereo amplifier project for computer. This projects is best for you. Before read detail of they we should read mono model on This is Super Small Power Amplifier BCL 1.2W by TDA7052. If you are seeking the circuit amplifies small-sized. I begs for to advise this circuit because tiny economize with the equipment is a little.
This is Super Small Power Amplifier BCL 1.2W by TDA7052. If you are seeking the circuit amplifies small-sized. I begs for to advise this circuit because tiny economize with the equipment is a little. And still can use force against large-sized get comfortablely ( I has tried already ) besides it still use volt power supply very wide be about 1.5V arrive at 15V as well. Regard as IC TDA7052 be worthwhile very much. For you who want to try build this circuit. I has model PCB give a friend tests to see with. Request have fun the circuit amplifies miniature please.

TDA 2050 Aamplifier

 
If you want to build hi-fi power amplifier the size about 30watt to 50Watt at good sound and build easy. I begs for to advise the circuit that builds with the integrated circuit. You wares IC TDA2050 then like very the circuit model class AB audio amplifier.
Thanks to its high power capability the TDA2050 is able to provide up to
35W true rms power into speaker 4 ohm load at THD =10%, VS =±18V, f = 1KHz and up to 32W into
8ohm load @THD = 10%, VS = 22V, f = 1KHz.Moreover, the TDA 2050 delivers typically 50W
music power into 4 ohm load over 1 sec at VS=22.5V, f = 1KHz
May take an interest want to try build already, try out this circuit use voltage Vcc +/- 25V.

Mini 40 watt audio car amplifiers using HA13001

From this 20watt Integrated Amplifier project. Some people say that expensive and want the main amplifier only. I recommend this project, it had a budget of only 5$. and is the main amplifier. They have size of power to speaker is 40 watts and use voltage of power supply is 12 volts so can apply right in car. They use the HA13001-IC is key parts so small and build easily.
How This Circuit works
When see a circuit as Figure 1 Many people would doubt that. This circuit will be amplified up to 40 watts. (If as the RMS will is about 17.5 watts at load 4 ohms). You do not insult it because the many circuits that were contained in IC1-HA13001 of Hitachi there. Makes a few external devices, and the output of IC1 that connects to the loud speaker will be connected on the bridge circuit types. So causes the output has a high power there.

Figure 1 the circuits use IC-HA13001
We do not fear that the speaker will be damaged easily. because in IC1 has the Automatic Shut-Off circuit (ASO) that use to protect the speaker. Thus You need to carefree it. and this circuit will use the power supply range between about 12-18 volts for its’ source.
How to builds this projects
This simple project starting with make the PCB which has copper layout as figure 2 before. Then solder all components as figure 3. We can solder directly the IC1 onto PCB so should take special care.

Figure 2 The PCB layout

Figure 3 The components layout for PCB
The power supply that can use a DC adapter but must provide current over up 1 amperes. Otherwise, when you accelerate the more volume, the sound will be broken and Adapter will malfunction.
The application this projects
This amplifier project use to amplify from the various sound generator such as The iPad or mobile phone or notebook computer’s etc. Or Modified into the old car stereo that repair difficult. We changed the set to the amplifier.
