PROGRAMMING THE LOOK-UP TABLE (LUT)
The following equation can be used to determine which resistor position setting, 00h – FFh, should be
written in the LUT to achieve a given resistance at a specific temperature.

a = 3.78964 for the 50kW resistor
a = 19.74866 for the 10kW resistor
DS1848-010
a = 8.394533 for both 10kW resistors
R = resistance desired at the output terminal
C = temperature in degrees Celsius
u, v, w, x, y, and z are calibration constants programmed into each of the corresponding look-up tables.
Their addresses and LSB values are given in Table 1 below. Resistor 1 variables are found in Look-Up
table 1 of the EEPROM, and Resistor 2 variables are found in Look-Up Table 2. After these values are
read, they should be overwritten with the appropriate temperature specific resistance settings. Copies of
these values can also be found in the User EEPROM memory.

When shipped from the factory, all other memory locations in the LUTs are programmed to FFh (except
bytes 00h-07h of Table 1 and 2 which may be factory programmed to values other than FFh).
Note: Memory locations 44h – 47h, which cover the temperature range (+96C to +102C), are outside
of the specified operating temperature range (-40C to +95C). However, the values stored in these
locations will act as valid resistance settings if the temperature exceeds +95C. Therefore, Dallas
Semiconductor recommends that the user program a resistance value into all LUT locations. Failure to do
so will result in the part being set to the default value.
