This YD1517p is a 18 pin DIP IC. It is a class B audio amplifier which gives 6 watt stereo output. In this article I’m sharing YD1517p audio amplifier circuit diagram and components list to build a simple stereo audio amplifier system for car audio or small portable audio device.
What is YD1517p IC?
YD1517p is a 18 pin audio amplifier IC. This is comes in plastic packaging and provides 6 watt stereo audio output. This IC comes in Class B audio amplifiers and it needs very less number of electronic components to work, So the total cost will be less compared with other audio amplifiers. The main feature of this IC is their is no Switch On or Switch OFF plop and thermally protected.
YD1517p Circuit Diagram
The input DC voltage is 14V and the output audio is 6 watt per channel. The supply voltage maximum input is 18V DC, so this circuit is safe in car audio amplifiers, because the Car battery voltage reaches to 15-16V in running condition.
