13. This parameter is not 100% tested.
11. RINL = [R
1. Typical values are for T
2. LSB: [V(RW)
3. ZS error = V(RW)
4. FS error = [V(RW)
5. DNL = [V(RW)
6. INL = V(RW)

9. Roffset = R
incremental voltage when changing from one tap to an adjacent tap.
Max( ) is the maximum value of the wiper voltage and Min ( ) is the minimum value of the wiper voltage over the temperature range.
Roffset = R
Max( ) is the maximum value of the resistance and Min ( ) is the minimum value of the resistance over the temperature range.
