The DS3906 is intended for low resistance, small stepsize applications. It contains three nonvolatile (NV), lowtemperature 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 I2CTM-compatible serial interface. Three address pins allow up to eight DS3906s to be placed on the same I2C bus. The DS3906 can also be factory cutomized to provide a variety of transfer functions depending on user requirements.
