The DS3903 contains three nonvolatile (NV) low temperature coefficient digital potentiometers, which can be accessed through a 2-wire bus. The DS3903 operates in both 3V and 5V systems, and it features a write-protect pin that can lock the positions of the potentiometers. An address pin allows two DS3903s to be placed on the same 2-wire bus.
