digital resistor
Hay everyone, I need a digitally controlled resistor. I don't want to use a digital pot because I need parallel interface. I looked around for a sample schematics using a DAC as a digital pot, but I could not find a solution. I think the DAC800 could do the job, but I am clueless on how to set it up as a variable resistor.
