I need a barcode in a PDF/A

as in the title, I need a (simple 128) barcode and I need the PDF/A standard. I know how to do both separately. But pdfx won’t run with latex so I cannot create a DVI and so on, which I need for the pst-barcode package:

! pdfTeX error (pdfmapline): not allowed in DVI mode (pdfoutput <= 0). pdfmapline

Is there a way to have a bar code and PDF/A without pst-barcode that works with pdfLatex? Thank you very much!

Edit: using the code in the answer below the following terminal output is produced (truncated a bit):
