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
HIGH VOLTAGE TOLERANT PINS
In many applications, the High Voltage will
only be present at the manufacturing
stage so as to “lock” the Non-Volatile 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.
