5. Typical values are for T_A = +25°C and 3.3V supply voltage.
6. LSB: [V(RW)₃₁ – V(RW)₀]/31. V(RW)₃₁ and V(RW)₀ are voltage on RW pin for the DCP register set to 1F 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)₃₁ – V_CC]/LSB.
9. DNL = [V(RW)_i – V(RW)_i-1]/LSB -1, for i = 1 to 31; i is the DCP register setting.
10. INL = [V(RW)_i – i • LSB – V(RW)]/LSB for i = 1 to 31

) is the maximum value of the wiper
voltage over the temperature range.
12. MI = |RW₃₁ – RW₀|/31. MI is a minimum increment. RW₃₁ and RW₀ are the measured resistances for the DCP register set to 1F hex and 00
hex respectively.
13. Roffset = RW₀/MI, when measuring between RW and RL.
Roffset = RW₃₁/MI, when measuring between RW and RH.
14. RDNL = (RW_i – RW_i-1)/MI, for i = 1 to 31.
15. RINL = [RW_i – (MI • i) – RW₀]/MI, for i = 1 to 31.
