NOTES:
3. Typical values are for TA = +25°C and 3.3V supply voltage.
4. LSB: [V(RW)127 – V(RW)0]/127. V(RW)127 and V(RW)0 are V(RW) for the DCP register set to 7F hex and 00 hex respectively. LSB is the
incremental voltage when changing from one tap to an adjacent tap.
5. ZSerror = V(RW)0/LSB.
6. FSerror = [V(RW)127 – VCC]/LSB.
7. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 127. i is the DCP register setting.
8. INL = [V(RW)i – (i LSB) – V(RW)0]/LSB for i = 1 to 127
9.
for i = 16 to 127 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.
10. MI =
|RW127 – RW0|/127. MI is a minimum increment. RW127 and RW0 are the measured resistances for the DCP register set to 7F hex and
00 hex respectively.
11. Roffset = RW0/MI, when measuring between RW and RL.
Roffset = RW127/MI, when measuring between RW and RH.
12. This parameter is not 100% tested.
13. tWC is the time from a valid STOP condition at the end of a Write sequence of I
2C serial interface, to the end of the self-timed internal non-volatile
write cycle.
14. 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.
Operating Specifications Over the recommended operating conditions unless otherwise specified. (Continued)
