Typical values are for TA = +25°C and 3.3V supply voltage. 5. 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. 6. ZS error = V(RW)0/LSB. 7. FS error = [V(RW)255 – VCC]/LSB. 8. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 255. i is the DCP register setting. 9. INL = [V(RW)i – i • LSB – V(RW)]/LSB for i = 1 to 255 10. VMATCH= [V(RWx)i -V(RWy)i]/LSB, for i = 0 to 255, x = 0 to 3, y = 0 to 3. 11. 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. 12. 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. 13. Roffset = RW0/MI, when measuring between RW and RL. Roffset = RW255/MI, when measuring between RW and RH. 14. RDNL = (RWi – RWi-1)/MI -1, for i = 1 to 255. 15. RINL = [RWi – (MI • i) – RW0]/MI, for i = 1 to 255. 16. RMATCH= [(Rx)i -(Ry)i]/MI, for i = 0 to 255, x = 0 to 3, y = 0 to 3. 17. 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. 18. 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. 19. Rpu is specified for the highest data rate transfer for the device. Higher value pull-up can be used at lower data rates. 20. This parameter is not 100% tested. Operating Specifications Over the recommended operating conditions unless otherwise specified.
