NOTES:
5. Typical values are for T_A = +25°C and 3.3V supply voltage.
6. LSB: [V(RW)₁₅ – V(RW)₀]/15. V(RW)₁₅ and V(RW)₀ are voltage on RW pin for the DCP register set to F hex and 0 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)₁₅ – V_CC]/LSB.
9. DNL = [V(RW)_i – V(RW)_i-1]/LSB -1, for i = 1 to 15; i is the DCP register setting.
10. INL = [V(RW)_i – i • LSB – V(RW)]/LSB for i = 1 to 15
11. _{TCV =}

[Max(V(RW)_i) + Min(V(RW)_i)] ⁄ 2 +165°C
for i = 5 to 15 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 = |RW₁₅ – RW₀|/15. MI is a minimum increment. RW₁₅ and RW₀ are the measured resistances for the DCP register set to 0F hex and 00
hex respectively.
13. Roffset = RW₀/MI, when measuring between R_W and R_L.
Roffset = RW₁₅/MI, when measuring between R_W and R_H.
14. RDNL = (RW_i – RW_i-1)/MI, for i = 1 to 15.
15. RINL = [RW_i – (MI • i) – RW₀]/MI, for i = 1 to 15.

[Max(Ri) + Min(Ri)] ⁄ 2 +165°C
for i = 5 to 15, 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. Limits should be considered typical and are not production tested.
18. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
