Electronic Wiring Diagram for Mono Car Audio Amplifier 20W using IC LM1875

RealAutoTips. - It is very nice if our car facilitated with car audio. When we drive our car we will avoid our tired and bored with play music and also hear religious speech. With audio car we also can hear many song using car audio. And now we thing that audio car to be urgent facilities in car, so almost all car facilitated with car audio.

But if your car now not yet facilitated with audio car, you don't worry you can add your car with audio car by your self. Audio car not separate with audio amplifier that needed to amplify the audio signal and we can hear from the speaker. So in this time we will give you one electronic wiring diagram for Mono Car Audio Amplifier 20W using IC LM1875.

You can realize this electronic wiring diagram for Mono Car Audio Amplifier 20W using IC LM1875 in real project. You can install the all components that needed into PCB layout and then you can use this wiring diagram to amplify your car audio signal.

Wiring Diagram Description

The Electronic Wiring Diagram for Mono Car Audio Amplifier 20W using IC LM1875 like in figure 1 above, we think this is the simple electronic wiring diagram. This is just another 20W audio amplifier circuit , but this time based on the LM1875 audio amplifier IC from National Semiconductors. With a 25V dual power supply LM1875 can deliver 20W of audio power into a 4 ohm speaker. The LM1875 requires very less external components and has very low distortion. The IC is also packed with a lot good features like fast slew rate, wide supply voltage range, high output current, high output voltage swing, thermal protection etc. The IC is available in TO-220 plastic power package and is well suitable for a variety of applications like audio systems, servo amplifiers, home theatre systems etc. (Source:Circuitstoday)
