How to make a low-pass filter for the amplifier. Hello Friends, in this post I made a high-gain low-pass filter. I have used 2 OP-AMP for this low-pass filter, one for the low frequency and the second for boosting the frequency. For this low-pass filter, I have used NE5532 IC. But in place of NE5532 IC, you can also use TL072 or 4558D IC. In this low-pass filter, you can control 45Hz-240Hz frequency. You can use this low-pass filter with any amplifier.
For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to www.pcbway.com for manufacturing my PCB. PCBWay is the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil, and PCB Assembly Services. 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. www.pcbway.com 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 Black PCB. But you can choose your PCB color. PCBWay provides a total of 9 color solder masks - 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 the 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.
