Amplifier ic 18W using HA13118

IC amplifier 18 watt circuit is an IC number HA13118 Hitachi Hard. That the IC will be integrated amplifiers, class AB. And this cycle is to use a bridge circuit. As a result, growth rates up to 55 dB. And pressure from 8-18 volt the current 1-2 amps, with less than 0.2% distortion at 1W. And response. frequencies from 30 Hz-30 kHz.
When entering the power supply circuit, and paid into the audio input. The audio is through VR1 adjusts the level of the audio signal. And pass the C1 coupling signal. The C2 eliminate the interference. From the audio signal to be sent through to the input pin on pin 3 of IC1. That this circuit to circuit in the form of bridge circuits or extension of the left navigation. And right channels together, to get a higher watt power. The observations from the pin 15 which is the output of left channel speakers are connected to one side. And the other side of the speakers are connected to the output of pin 8, which is the output of the right. The C7 and C8 acting feedback signal to the circuit’s frequency response is better. The C9, C10, R1 and R2 will serve removed the devices. And C11, C12 serve to filter the light properly to prevent any noise shock.

IC amplifier stereo 10W +10W with ic TDA2009

The IC 10W +10 W stereo amplifier circuit design that looks similar to the IC 8W +8 W stereo amplifier circuits of the previous album.But it will change the IC amplifier as a number TDA2009.Within the IC for circuit amplifiers, Hi-Fi class AB.And output short circuit protection sectors as well.But there will be different according to the properties of the IC. The TDA2009 IC is to qualify from the power supply 8-24 volts, the current maximum of 1-2 amp.An output voltage watt 10 watt 24 volt load 4 ohms, 0.351% distortion at a frequency 1 kHz, frequency response from 10 Hz-50 kHz at -3 dB to 36 dB of gain and the strength. input signal at 100 mV.
When raising the power supply circuit and input into the audio input.The audio input left channel and right channel. Will it work the same.So I explained the principles of the left channel only one box.Signal through C1 for protection dc electric To interfere with IC.
Then go to the input signal to pin 5 of IC.The non inverting pin will not extend to phase signals. The output from pin 8. Through C8 and to prevent DC and increase the low frequency response the better,then sent to the speaker.The C10 and C11 serve to filter the light to protect the smooth sound … Tub..Tub… at the time of launch noise.

Small audio amplifier IC 7w using lm383

This circuit, will help expand the sound small. such as radio, sound out, including CD WALKMAN. To the more powerful sound.The amplifier circuit can be up to 7 watts. Enough to use a good listening room.And most importantly is a very simple circuit.
Operation of the circuit. be Input signal is coupling with the C1.Passed into the pin 1 of IC1 number LM383. Amplifier output from the pin 4.Through C3 increase in low frequency stability better, before leaving to the speaker. The R2 and R3 set the gain 100 times. Which is calculated from the (R3/R4) +1.The C2 functions help in frequency response.
