I am trying to make a constant current source using LT3092 .My DAC maximum output is 3.3V and at that time the current source needs to generate a current of 20mA.
For generating 20mA the RSET(R1 in schematic) value needs to be 165 Ohm . Please see my circuit below.
The issue what I am facing is my load will come in series with RSET and this is changing thedesired current.May I know is there any way to solve this issue.
Below is the circuit with load.You can see that the current is changed.
Is there any way to make a DAC controlled constant current source using this IC
