Hello there,
I am designing a PCB for testing an ASIC taped out a few months back. I wonder if anyone knows a single component that can output a digitally current from 0 to 2mA, a DAC basically.
Of course, it is always possible to add an opamp to a voltage DAC to make it work as a current source, but perhaps someone knows a single component that does that. If so, please...
The resolution is not so important, it will be used to set some bias current for the ASIC.
Thank you.
