General Description
The DS3903 contains three nonvolatile (NV) low tem-
perature coefficient digital potentiometers, which can
be accessed through a 2-wire bus. It 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.
