NOTES: (Continued)
8. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 127. i is the DCP register setting.
9. INL = [V(RW)i – (i LSB) – V(RW)0]/LSB for i = 1 to 127
10.
for i = 16 to 127 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.
11. 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.
12. Roffset = RW0/MI, when measuring between RW and RL.
Roffset = RW127/MI, when measuring between RW and RH.
13. RDNL = (RWi – RWi-1)/MI -1, for i = 1 to 127.
14. RINL = [RWi – (MI i) – RW0]/MI, for i = 1 to 127.
15.
for i = 16 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.
16. tWC is the time from the end of a Write sequence of SPI serial interface, to the end of the self-timed internal non-volatile write cycle.
17. Rpu is specified for the highest data rate transfer for the device. Higher value pull-up can be used at lower data rates.
18. Limits should be considered typical and are not production tested.
