ams AG introduced the AS5600,a magnetic rotary position sensor which makes it easier than ever before to replace ... the output of a potentiometer (which is a variable resistor).

The digital pots replace mechanical potentiometers and provide advantages such as remote ... The DCP is implemented with a combination of resistor elements, R, connected in series and CMOS switches, ...

To get around the built-in short-circuit protection he needed a potentiometer to limit the current while allowing for adjustments. His first circuit used a resistor salvaged from an AT supply and ...
