CA3080 question

Calling all CA3080 OTA experts!

Is there a certain and repeatable transconductance figure over the usable
range of control current from sample to sample for the CA3080 OTA?  I can't
really tell from the data sheet.  I'm considering an application where 2
OTA outputs need to be the same (like better than 5%) over the range of
control current.  I'm not sure what the range of the control current will
be but I can use a range that will optimize the match.

I guess what I'm asking is: Is the 3080 OTA transconductance repeatable and
the same across all samples?
