pin out of LTP current source?

[myhrrhleine]

Hello,
I am looking for an OP-AMP which provides pin out access to the LTP current.
I would like to have control of the current.
Anyone know of such a device?

LM3080 "transconductance op amp", Gilbert cell analog multipliers will let you do that

maybe some adjustable bias/BW op amps - but I don't remember any really explaining which currents are being adjusted in detail

LM13700 Maybe?

Good luck.
