I have an application where I need to replace a mechanical potentiometer with a digital one. The problem I have is I want to use 8 5v inputs to control the resistance (eg. 8 control pins on a pc parallel port). Is there an IC that will address this, or is there a circuit that can be built? I can find 256 tap digi pot IC's but they all have an increment/ decrement thing going on. Please Help TY
