AFE (analog front end) is commonly used, but I'm not sure if implies
more than we want here.  Lars, Michael this is more your area than
mine - what do you think?

We could call it an amplifier and be done with it but that wouldn't
really encompass the fact we are also changing it's apparent measurement
from voltage to current because we know enough about the circuit to do
so...
