Perhaps you could clarify, where is the control voltage coming from, for example is it something like zero to 5 volts coming from the center tap of a potentiometer connected between the suppl and ground, and what are you wanting the current to flow through and is that load connected on one side to the positive rail or ground?What input voltage range? What current do you want?
Thank you, Eric. I am at work now but will share when i am back home.hi myil.
I have the LM13700 LTspice model that I use.
Post your basic circuit and the required project specification and I will create a sim circuit.

I want a variable current source depending on the input voltages.I understand why this part looks good but I think there are better parts.
What input voltage range? What current do you want?
Thank you, Erichi @myil
Downloaded the items in post #9, will try to post back by this time tomorrow.

Do you mean 100uSec.?
Or is that micro Siemens (micro mhos?) It is a voltage controlled current source.Thank you, Eric
hi DickCappels,Or is that micro Siemens (micro mhos?) It is a voltage controlled current source.
What input voltage range? What current do you want?
Input voltage 0 to 5V.I want a variable current source depending on the input voltages.
Hi ronsimpson,Input voltage 0 to 5V.
Output voltage 0 to 100 amps. (mA, uA??)
What is the load like. Resistive load to ground? (5 ohms sitting on ground?)
This information is important. This circuit translates the voltage from IC2 to current in the load.

Hi DickCappels,Then there is the Howland current source that does not require any special parts.
Why do you want to specifically use the LM13700?
