Using as simple a setup as possible, what would my options be for a variable digitally controlled current source be? The main current driver would be a power mosfet. I'm thinking along the lines of 0-1 amp 256 steps. 0 doesn't need to be one of them but not more than 5ma on the lowest setting. Linearity would be preferred but not required.
Anyone else have alternatives? Something I could do with discrete components? I'd rather not buy a digital pot, and I wouldn't mind 0-5 amps with 11 bits of range.
