digital rezistor
I guess it would be unipolar because that would be the way a regular carbon resistor would work. The voltage would be +5. 8-bits would be the range 0-255; I would need a resistance range of 750Ω - 3.5kΩ, and the decimal value 127 would provide 2.1kΩ.
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...
