LM4870 PCB Group Buy

Wynand · 10th January 2006, 01:41 PM

Has there been a group buy with the Evaluation PCB for the LM4870 from National?

If not would there be an interest for it?

if you take a close look at the Nat Semi ev board it would appear that you'll have a tricky time mounting a heatsink to the device. it also uses a difficult to find socket for the chip.

there are a lot of boards out there for $7 or $8

I saw the heatsink issue.

Where can I get those PCBs.
