9. INL = [V(RW)i – (i • LSB – V(RW)0)]/LSB for i = 1 to 255.
10. TCV
=
-------M-----a----x----(--V----(---R-----W------)--i--)---–-----M-----i--n----(--V-----(--R-----W------)--i--)------ × ------1----0---6-------
[Max(V(RW)i) + Min(V(RW)i)] ⁄ 2 +165°C
for i = 16 to 240 decimal, T = -40°C to +125°C. Max( ) is the maximum value of the wiper
voltage and Min ( ) is the minimum value of the wiper voltage over the temperature range.
11. MI = |R255 – R0|/255. R255 and R0 are the measured resistances for the DCP register set to FF hex and 00 hex respectively.
Roffset = R0/MI, when measuring between RW and RL.
12. Roffset = R255/MI, when measuring between RW and RH.
13. RDNL = (Ri – Ri-1)/MI, for i = 16 to 255.
14. RINL = [Ri – (MI • i) – R0]/MI, for i = 16 to 255.
15. TCR
=
----[---M-----a----x----(--R-----i--)---–-----M-----i--n----(--R-----i--)--]---- × ------1---0----6-------
[Max(Ri) + Min(Ri)] ⁄ 2 +165°C
for i = 32 to 255, T = -40°C to +125°C. Max( ) is the maximum value of the resistance and Min ( ) is
the minimum value of the resistance over the temperature range.
16. Limits established by characterization and are not production tested.
17. tWC is the time from a valid STOP condition at the end of a Write sequence of a I2C serial interface Write operation, to the end of the self-timed
internal non-volatile write cycle. The Acknowledge Polling method can be used to determine the end of the non-volatile write cycle.
18. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested.
