Rev 3; 3/07  
Triple 128-Position Nonvolatile Digital  
Variable Resistor/Switch  
4/DS3905  
General Description  
Features  
The DS3904/DS3905 contain three nonvolatile (NV) low  
temperature coefficient, variable digital resistors. Each  
resistor has 128 user-selectable positions. Additionally,  
the DS3904/DS3905 have a high-impedance setting that  
allows each resistor to function as a digital switch. The  
DS3904/DS3905 can operate over a 2.7V to 5.5V supply  
voltage range, and communication with the device is  
achieved through a 2-wire serial interface. Address pins  
allow multiple DS3904/DS3905s to operate on the same  
two-wire bus. The DS3904 has one address pin, allow-  
ing two DS3904s to share the bus, while the DS3905  
has three address pins, allowing up to eight DS3905s to  
share a common bus. The low-cost and small size of the  
DS3904/DS3905 make them ideal replacements for con-  
ventional mechanical trimming resistors.  
♦ Three 20kΩ, or Two 20kΩ and One 10kΩ, 128-  
Position Linear Digital Resistors  
♦ Resistor Settings are Stored in NV Memory  
♦ Each Resistor has a High-Impedance Setting for  
Switch Operation to Control Digital Logic  
♦ Low Temperature Coefficient  
♦ 2-Wire Serial Interface  
♦ 2.7V to 5.5V Operating Range  
♦ -40°C to +85°C Industrial Temperature  
♦ Packaging: 8-Pin µSOP for DS3904, 10-pin µSOP  
for DS3905
