I want to design an adjustable current source.

Maximum current: 500mA

Minimum current: 100mA.


I have seen the application note AN-968.

I am thinking of using a DAC and the circuit in figure 5.

I have tried to simulate with LTspice, but i doesn't work,

Is the schematic correct? I am not able to understand the feedback.
