How to breadboard a OPA454AIDDAR-TI_SO-PowerPAD-8_ThermalVias

and OPA1656IDR - TI 8-Pin SOIC

Been trying to find some pcb adaptors, but I have not had much luck. Can find normal 8 pin, 14 pin DIL but nothing for SMD components

Any advice please, and point me in the right direction.

 

My first advice is to include the details of the item you want to connect to. I NEVER lookup data using posted links, and without the physical dimensions you can not even create a drawing of what is needed. So YOU need to retrieve the required information and put it in a post.
You are asking for services that commercial rates would apply for.

 

The OPA165x is a 50mhz amp. It will not be happy with long wires. I would use a little board something like the first picture. Put the bypass caps on top of the IC and connect from power lead to power lead over the top.
The resistors need to touch the IC or very close. There are many different types of boards like this.

This will work at low speeds but not at 50mhz.

Do not do this. The white board adds too much. (capacitance and inductance)

Its all there, packages are TI_SO-PowerPAD-8_ThermalVias and TI 8-Pin SOIC

 

I try to break all circuits down into blocks before going for a full pcb, and use the white breadboards or stripboard veroboard. But this equally tends to have long tracks and inherent capacitance and inductance.

Are you able to buy in prepopulated mini adapter pcb's.

I have managed to find some mini adapter pcbs that I think might do. The description says
IC adapter Socket SOP8/TSSOP8/SOIC8/SSOP8


I think SOP8 is the same as SO-PowerPAD-8 but not sure. But it does not have the solder pad in the middle.

Maybe for testing the IC will not heat up enough and the transfer pad is not needed. But then again I do not know.

But I was thinking that maybe I needed to practice upon a couple of them adapters, which were totally correct, including solder transfer pads, before I embark on a proper pcb.

Maybe if anyone knows where I can buy a scrap or new 6inch x 6inch board with a few of the IC pads on them.

I think I am safe with SOIC8 being the correct one.

 

Without the heatsink pad in the center the IC will run hotter. No question. It will work.
The cost of small quick turn 2 layer PCBs are low. Make a board and get it back in a week. Your first board will have problems. So, find out what those problems are now, before the problems are in the middle of a large, big money, PCB.
