Applications Information
Power-Supply Decoupling
To achieve the best results when using the DS3911,
decouple the power supply with a 0.01FF or 0.1FF capac-
itor. Use a high-quality ceramic surface-mount capacitor
if possible. Surface-mount components minimize lead
inductance, which improves performance, and ceram-
ic capacitors tend to have adequate high-frequency
response for decoupling applications. Likewise, a decou-
pling capacitor should be placed from VREF to GND.
SDA and SCL Pullup Resistors
SDA is an I/O with an open-collector output that requires
a pullup resistor to realize high-logic levels. A master
using either an open-collector output with a pullup resis-
tor or a push-pull output driver can be used for SCL.
Pullup resistor values should be chosen to ensure that
the rise and fall times listed in the I2C AC Electrical
Characteristics table are within specification. A typical
value for the pullup resistors is 4.7kI.

The DAC OFFSET is a set of registers assigned to hold the pulse-density modulation profile for the associated DAC.
The values in this table are multiplied by four and added to the corresponding value in the LUT table to determine
the set point for the associated DAC. In all four DAC tables, the DAC OFFSET registers are formatted the same. The
OFFSET registers increase in 16NC steps from -8NC to +88NC. Below -8NC the DAC OFFSET is indexed at 0xF8. See
the Offset Temperature Mapping table for full register to temperature mapping. Register F8h defines the -40NC to
-8NC DAC OFFSET value, register F9h defines the -8NC to +8NC DAC OFFSET value, and so on.
