OpAmp for hypex UCD180 LP OEM

[rdalem]

I want to increase the gain on a UCD180 LP OEM amplifier with supply SMPS400A180. Current gain is Av 13.1 dB And I could wish for 25-26 dB. I want to boost with a suitable OpAmp.

I would build a pre amp stage off the board.
TL072p will do it.

Ok, so TL072 will do. How then to build a pre amp from the board? Do you mean the UCD180 board.

@rdalem The input buffer in the datasheet is fairly simple. Is your source single-ended or balanced?

 

[rdalem]

Source is balanced.

Are you referring to section 6 of the hypex manual?

I build this one, same topo as on page 6.
I have gerber files when you want them to order pcb.

Below the gerber file.

You can use all kinds of dual opamps like LM4562, NE5532, TL072 an6 with SO to DIP adapter a lot more.

Thank you very much @Monstercore.
