General Description
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-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. Contact mixedsignal.apps@dalsemi.com
for additional information.
