NOTES:
7. Typical values are for TA = +25°C and 3.3V supply voltages.
8. LSB = [V(RW)127 – V(RW)0]/127. V(RW)127 and V(RW)0 are V(RW) 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.
9. ZS error = V(RW)0/LSB.
10. FS error = [V(RW)127 – VCC]/LSB.
11. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 127. i is the DCP register setting.
12. INL = [V(RW)i – i LSB – V(RW)0]/LSB for i = 1 to 127
13.
For i = 8 to 127decimal, 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.
14. 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.
15. Roffset = RW0/MI, when measuring between RW and RL.
Roffset = RW127/MI, when measuring between RW and RH.
16. RDNL = (RWi – RWi-1)/MI -1, for i = 8 to 127.
17. RINL = [RWi – (MI i) – RW0]/MI, for i = 8 to 127.
18.
for i = 8 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.
19. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
20. It is preferable to ramp up both the VLOGIC and the VCC supplies at the same time. If this is not possible, it is recommended to ramp-up the VLOGIC
first followed by the VCC.
21. VMATCH = [V(RWx)i - V(RWy)i]/LSB, for i = 1 to 127, x = 0 to 1 and y = 0 to 1.
22. RMATCH = (RWi,x - RWi,y)/MI, for i = 1 to 127, x = 0 to 1 and y = 0 to 1.
