Table 2. DS3906 Resistor Registers
* Writing a value greater than 3Fh to any of the resistor registers makes the corresponding resistor go High-Z. Position 3Fh is the
maximum position.
makes the corresponding resistor go High-Z. Plots for
both resistor sizes are shown on the front page of this
data sheet. It can be seen that, when an external resis-
tor is connected in parallel with the DS3906’s resistors,
the effective resistance is linear and capable of achiev-
ing sub-ohm and ohm steps.
The resistor settings are stored in EEPROM memory. It
is important to point out that the DS3906 EEPROM is
organized in 2-byte pages. This is transparent when
reading from the device or when performing single byte
writes. However, this limits the maximum number of
bytes that can be written in one I2C transaction to two.
Furthermore, the multiple byte writes must begin on
even memory addresses (00h, 02h, …., F8h, etc).
Additional information is provided later in the I2C
Communication section . Example communication
transactions are provided in Figure 3.
