LM1876T Flat Frequency Amplifier

Hello Friends, in this post I make a 40 Watt Stereo amplifier using LM1876 IC. This is a class AB amplifier, which can deliver up to 20 Watt RMS output per channel at 8Ω ±24V, Test frequency 1khz. This IC is specially designed for High-End Stereo Amplifiers, for its low noise distortion. This is a flat frequency amplifier that has in-built short circuit protection, and over-voltage protection, So for this reason, this IC is a little bit more expensive than other IC. All frequencies are very clear. You can hear all frequencies very clearly. Overall the sound quality of this amplifier is very good. If you make this amplifier you will not be disappointed. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to for manufacturing my PCB. PCBWay are the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil and PCB Assembly Service. Here you get, 100x100mm 2 Layer PCB only at $5, And processing time within 24 hours. And they distribute, worldwide. The more you order, the less price you have to pay.

You just need to upload the Gerber File, and select the quantity, color, silkscreen, thickness etc. Then select your country, and shipping method and then Pay. will deliver your PCB within 7-10 days.

After one week I received my PCB. You can see the PCB quality, it's awesome. I have ordered Yellow PCB. But you can choose your PCB color. PCBWay provides a total of 9 color solder mask - Green, Blue, Red, Purple, Black, White, Yellow, Matte Black, and Matte Green. On PCBWay you can get 100x100mm 2 Layer PCB only at $5. Maximum size PCB you can get 500x1100mm. And maximum Layer is up to 14 Layers. And If you order PCB the first time at PCBWay, then you get a $5 discount coupon. So upload your Gerber today and get the best quality PCB.
