Hi Velleman,

Im currently using your K8055 (with use from C++) for different applications, and
it works good.

HOWEVER, I would very much like to card to have MULTIPLE AD entrencies (strappable), where I could mount resistors for different amplification of input !!!

that would make it easier to switch between usages for your card, I need the two input AD
ports to have different sensitivity in my different applications.
(it would do with two mountable strappable resistors per port AD1/AD2, for the resistors
you now have as optional mount for a single resistor)

Thank you for the feedback.

Adjust the gain high enough using the fixed resistors and then attenuate the input for the other application using an external voltage divider.

Sounds like you could use an op-amp.
