In some applications, PCB area is a criteria for device
selection.
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.

Characterization curves of the resistor temperature
coefficient (Tempco) are shown in
Figure
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

High Voltage support (V
is for compatibility with the non-volatile devices.
