For some of our prototypes we are looking for high resistance digital potentiometers. We need to replace several analog 1-2 Mohm rotary potentiometers at 9-18V with digital ones. Do you also produce Digipotis in that range? We did not find the required specifications in your products portfolio. Do you alternatively offer any other products, which could work to replace these high resitance rotary potentiometers with a digital solution (at up to 18V prefferably)?
