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

It operates in both 3V and 5V systems, and it

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. Features.
Three 128-Position Linear Potentiometers (Two 10kΩ, One 90kΩ).
NV Wiper Storage.
0 to 5.5V on Any Potentiometer Terminal Independent of VCC.
Low End-to-End Temperature Coefficient.
Operates on an Industry-Standard 2-Wire Bus.
Write-Protect Pin.
Supply Voltage: 3V or 5V.
Oper.
