DS3906
Triple NV Low Step Size Variable
Resistor Plus Memory
_____________________________________________________________________

Detailed Description
The DS3906 contains three variable resistors plus a
user EEPROM. The block diagram illustrates these in
addition to the registers that control the resistors. The
following sections provide detailed information about
the DS3906.
Memory Organization
The DS3906 contains 16 bytes of User EEPROM plus 3
NV resistor registers. Refer to Table 1. Communication
with the memory/registers is achieved through the I2C-
compatible serial interface and is described in subse-
quent sections.
Resistor Registers/Settings
Each of the three resistors in the DS3906 has its own
control register used to set the resistor position. Refer
to the block diagram and Table 2. Each resistor has 64
positions plus a high impedance state. The nominal
resistance values for each position is listed in Table 3.
Resistors 0 and 1 have the same full-scale resistance,
which is different than resistor 2. As shown in Table 3,
the resistors have a pseudo-log response (resistance
vs. position) when used without an external parallel
resistor. Valid resistor settings are 00h to 3Fh. Writing a
value greater than 3Fh to any of the resistor registers
