[sdiy] simple 2164 linear to expo CV?

can a single 2164 cell be used to convert a linear voltage to roughly an
exponential voltage?

this isn't for controlling anything accurate like pitch, so I don't
think I need temperature compensation and stuff.

basically i have some already finished modules (mfos vcas and vcfs) that
only have linear CV inputs. i have a little cv output interface with a
bunch of linear faders in them that i use to control these and would
like to make a really simple 'linear to expo' CV module to use between
these so the controls feel more natural.

seems like I could just put a target DC value, say 5V into the 2164 and
attenuate that with the linear CV to get an exponential CV output?
