NOTES:
3. Typical values are for TA = +25°C and 3.3V supply voltage.
4. 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.
5. ZS error = V(RW)0/LSB.
6. FS error = [V(RW)127 – VCC]/LSB.
7. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 127. i is the DCP register setting.
8. INL = [V(RW)i – i LSB – V(RW)]/LSB for i = 1 to 127
9. VMATCH = [V(RWx)i – V(RWy)i]/LSB, for i = 1 to 127, x = 0 to 3 and y = 0 to 3.
10.
for i = 16 to 112 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. 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.
12. Rpu is specified for the highest data rate transfer for the device. Higher value pull-up can be used at lower data rates.
13. This parameter is not 100% tested.
Operating Specifications Over the recommended operating conditions unless otherwise specified. (Continued) Parameters with MIN
and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested. (Continued)
