PCB Area Requirements
In some applications, PCB area is a criteria for device
selection.
Table 8-2
shows the package dimensions
and area for the different package options. The table
also shows the relative area factor compared to the
smallest area. For space critical applications, the QFN
package would be the suggested package.

RESISTOR TEMPCO
Characterization curves of the resistor temperature
coefficient (Tempco) are shown in
Figure
2-32,
Figure
2-52, and
Figure
2-72.
These curves show that the resistor network is
designed to correct for the change in resistance as
temperature increases. This technique reduces the
end to end change is R
resistance.
