Maximum is determined by tR and tF.
For Cb = 400pF, max is about 2k
Ω ~ 2.5kΩ.
For Cb = 40pF, max is about 15k

NOTES:
7. Typical values are for TA = +25°C and 3.3V supply voltage.
8. LSB: [V(RW)127 – V(RW)0]/127. V(RW)127 and V(RW)0 are V(RW) for the DCP register set to FF hex and 00 hex respectively. LSB is the
incremental voltage when changing from one tap to an adjacent tap.
9. ZS error = V(RW)0/LSB.
10. FS error = [V(RW)127 – VCC]/LSB.
11. MI =
|R127 – R0|/127. R127 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 = R127/MI, when measuring between RW and RH.
13. RDNL = (Ri – Ri-1)/MI - 1, for i = 32 to 127.
14. RINL = [Ri – (MI i) – R0]/MI, for i = 32 to 127.
15.
for i = 32 to 127, T = -40°C to +85°C. Max( ) is the maximum value of the resistance and Min ( ) is the
minimum value of the resistance over the temperature range.
16. This parameter is not 100% tested.
17. VIL = 0V, VIH = VCC.
18. These are I2C-specific parameters and are not directly tested, however, they are used in the device testing to validate specifications.
19. 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.
20. The ramp must be >0.2V/ms at any voltage <2.7V starting from 0VDC. A power down to any voltage other than 0V is not included in the ramp
rate spec and may result in improper operation.
