Dual, Temperature-Controlled Resistors with
Internally Calibrated Monitors
____________________________________________________________________

Variable Resistors
The value of each variable resistor is determined by
a temperature-addressed look-up table, which can
assign a unique value (00h to FFh) to each resistor for
every 2°C increment over the -40°C to +102°C range
(see Table 3). See the Temperature Conversion section
for more information.
The variable resistors can also be used in manual
mode. If the TEN bit equals 0, the resistors are in manu-
al mode and the temperature indexing is disabled. The
user sets the resistors in manual mode by writing to
addresses 82h and 83h in Table 01 to control resistors
0 and 1, respectively.
Memory Description
Main and auxiliary memories can be accessed by two
separate device addresses. The Main Device address
is A2h (or value in Table 01 byte 8Ch, when ADFIX = 1)
and the Auxiliary Device address is A0h. A user option
is provided to respond to one or two device addresses.
This feature can be used to save component count in
SFF applications (Main Device address can be used)
or other applications where both GBIC (Auxiliary
Device address can be used) and monitoring functions
are implemented and two device addresses are need-
ed. The memory blocks are enabled with the corre-
sponding device address. Memory space from 80h and
