NOTES:
5. Typical values are for TA = +25°C and 3.3V supply voltage.
6. LSB: [V(RW)255 – V(RW)0]/255. V(RW)255 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.
7. ZS error = V(RW)0/LSB.
8. FS error = [V(RW)255 – VCC]/LSB.
9. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 255. i is the DCP register setting.
10. INL = [V(RW)i – i • LSB – V(RW)0]/LSB for i = 1 to 255.
11. VMATCH= [V(RWx)i -V(RWy)i]/LSB, for i = 0 to 255, x = 0 to 3, y = 0 to 3.

wiper voltage over the temperature range.
13. MI = |RW255 – RW0|/255. MI is a minimum increment. RW255 and RW0 are the measured resistances for the DCP register set to FF hex and
00 hex respectively.
14. Roffset = RW0/MI, when measuring between RW and RL.
Roffset = RW255/MI, when measuring between RW and RH.
15. RDNL = (RWi – RWi-1)/MI -1, for i = 16 to 255.
16. RINL = [RWi – (MI • i) – RW0]/MI, for i = 16 to 255.
17. RMATCH= [(Rx)i -(Ry)i]/MI, for i = 0 to 255, x = 0 to 3, y = 0 to 3.

volatile write cycle.
21. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested.
