Hi,
I am replacing an analog potentiometer with a digital one.
I'm using the AD5220 digital potentiometer and connecting a 9v battery with a 5v 7805 voltage regulator.
My question is, when the battery is connected to the digital potentiometer via the voltage regulator, will the battery be drained even when not in use or will it only be used when the buttons are pressed from the digital potentiometer?
Should I incorporate a fixed on/off switch into my design?
Thanks,
