Could someone check my design?

jacob-t over 10 years ago

Hi Guys

I'm totally new to this. I'm trying to build a 4 channel opamp (boost my signal about 100x)

I'm hoping someone has the time to quickly check my design and see if it makes sense and perhaps let me know how to improve it.

Thanks

Jacob

Hi,

At least capacitors should be added on the supply...
I don"t know the purpose of your circuit but you should add at least a small one capacitor (10 to 100 nF) placed near the power supply input pins of the LM324, and a electrolytic caacitor (few µF) rignt after the supply input connector.
En large 24V supply trace, and for the GND you can enlarge the trace or better add a GND plane (polygon).

You mean to filter the input?

Just have a look at your component placement. For example, switching the positions of R1 and R2 may improve your track routing.
