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

These curves show that the resistor network is
designed to correct for the change in resistance as
temperature increases. This technique reduces the

HIGH VOLTAGE TOLERANT PINS
In many applications, the High Voltage will
only be present at the manufacturing
stage so as to “lock” the Nonvolatile wiper
value (after calibration) and the contents
of the EEPROM. This ensures that since
High Voltage is not present under normal
operating conditions, these values can not
be modified.
