AD8232-EVALZ ease of modification?

Category: Hardware
Product Number: AD8232-EVALZ
Software Version: N/A

I'm planning a university-level course in embedded medical systems, and am considering using the AD8232 for student use as a front-end preamp. The issue: we don't have any soldering facilities other than a simple soldering iron, and it's not clear that will work well with the AD8232 LFCSP package. There's a SparkFun breadboard that sets up the AD8232 with some canned filter choices, but those choices don't work well for this course.

I though another option might be using the eval board (AD8232-EVALZ), with the hopes that I could then easily change the filter setup to have students see the effects of different filters. So the question: how easy is it to swap the resistors & caps on the eval board with just a soldering iron? Easy, or not really feasible? The board is set up for 7-25Hz operation, whereas I would like to have a much broader range preamp and have the students run DSP after that as a comparison.

Thanks,

Joel

  • Hi Joel,

    Have you checked out the user guide for AD8232's evaluation board? You can access it here. Please also see picture below:

    The evaluation board uses surface mount components, I see no problem modifying the RC components by a soldering iron alone - this is also what we usually use. There is also a default filter configuration shown in the user guide that may help you.

    Hope this helps!

  • Thanks, Kristine! I have seen the eval-board user guide, but wasn't sure if the mounting was SMT, or if that meant it could/couldn't be easily soldered (before going into teaching, I worked in CPU design and debug, so never really worked hands-on with PC boards).

    I'll give the SMT soldering a try.
