NOTES:
5. Typical values are for TA = +25°C and 3.3V supply voltage.
6. LSB: [V(RW)15 – V(RW)0]/15. V(RW)31 and V(RW)0 are voltage on RW pin for the DCP register set to 0F 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 – VCC]/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.
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 1F hex and 00
hex respectively.
13. Roffset = RW0/MI, when measuring between RW and RL.
Roffset = RW15/MI, when measuring between RW and RH.
14. RDNL = (RWi – RWi-1)/MI, for i = 1 to 15.
15. RINL = [RWi – (MI i) – RW0]/MI, for i = 1 to 15.
16.
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. Temperature limits established by characterization and are not production tested.
