I want to design an adjustable current source.
Maximum current: 500mA
Minimum current: 100mA.
I have seen the application note AN-968. http://www.analog.com/static/imported-files/application_notes/AN-968.pdf
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.
