NOTES:
8. Typical values are for TA = +25°C and 3.3V supply voltages.
9. 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.
10. ZS error = V(RW)0/LSB.
11. FS error = [V(RW)255 – VCC]/LSB.
12. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 255. i is the DCP register setting.
13. INL = [V(RW)i – i LSB – V(RW)0]/LSB for i = 1 to 255
14.
for i = 16 to 255 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.
15. 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.
16. Roffset = RW0/MI, when measuring between RW and RL.
Roffset = RW255/MI, when measuring between RW and RH.
17. RDNL = (RWi – RWi-1)/MI -1, for i = 16 to 255.
18. RINL = [RWi – (MI i) – RW0]/MI, for i = 16 to 255.
19.
for i = 16 to 255, 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.
20. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
