Triple NV Low Step Size Variable  
Resistor Plus Memory  
General Description  
Features  
♦ Three Programmable Resistors for Low Step-Size  
The DS3906 is intended for low resistance, small step-  
size applications. It contains three nonvolatile (NV), low-  
temperature coefficient, variable digital resistors that  
are capable of ohm and subohm increments when  
used in parallel with a fixed external resistor. All three of  
the DS3906’s resistors have 64 positions (plus a high-Z  
state) with a pseudo-log response cleverly chosen to  
have a linear equivalent resistance when paired with an  
external resistor (see graphs below). The DS3906 also  
contains 16 bytes of user EEPROM that, in addition to  
the resistors, are controlled through an I2C™-compati-  
ble serial interface. Three address pins allow up to  
eight DS3906s to be placed on the same I2C bus.  
Applications (Ohm and Subohm)  
♦ Resistor Settings are NV  
♦ 16-Byte NV User Memory (EEPROM)  
2
♦ I C-Compatible Serial Interface  
♦ Up to 8 Devices Can be Multidropped on the  
2
Same I C Bus  
♦ Low Power Consumption  
♦ Wide Operating Voltage (2.7V to 5.5V)  
♦ Operating Temperature Range: -40°C to +85°C  
Ordering Information  
The DS3906 can also be factory cutomized to provide a  
variety of transfer functions depending on user  
requirements. Contact mixedsignal.apps@dalsemi.com  
for additional information.
