NOTES:
5. Typical values are for T_A = +25°C and 3.3V supply voltage.
6. LSB: [V(R_W)₁₂₇ – V(R_W)₀]/127. V(R_W)₁₂₇ and V(R_W)₀ are V(R_W) 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.
7. ZS error = V(RW)₀/LSB.
8. FS error = [V(RW)₁₂₇ – V_CC]/LSB.
9. DNL = [V(RW)_i – V(RW)_i-1]/LSB-1, for i = 1 to 127. i is the DCP register setting.
10. INL = [V(RW)_i – (i • LSB) – V(RW)₀]/LSB for i = 1 to 127

MaxVRW_i + MinVRW_i  2 +165°C
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.
12. 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.
13. Roffset = RW₀/MI, when measuring between RW and RL.
Roffset = RW₁₂₇/MI, when measuring between RW and RH.
14. RDNL = (RW_i – RW_i-1)/MI -1, for i = 16 to 127.
15. RINL = [RW_i – (MI • i) – RW₀]/MI, for i = 16 to 127.

+ 165 °C
for i = 16 to 127, 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.
17. t_WC is the time from a valid STOP condition at the end of a Write sequence of I2C serial interface, to the end of the self-timed internal non-volatile
write cycle.
18. Limits should be considered typical and are not production tested.
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.
