Hi, I am using a MCP4341 quad digital potentiometer, and I need to be able to pass 5mA through it for the current loop in a MIDI circuit.
Why? The hardware cannot be altered, but I can do some software switching of signals and pass 5volts through one end of the pot to the wiper and out to a MIDI jack.
However, the data sheet states 2.5mA as the maximum current through either the A, B or wiper terminals. If I switch things in software I can run some of the pots in parallel. Will that allow a higher maximum current?
Or, perhaps 5mA constant is not required by MIDI?
Or, is there something else that can be done?
thanks
