TIMING CHARACTERISTICS (continued)
(Figure 3; V DD = +2.7V to +3.6V (MAX5380), V DD = +4.5V to +5.5V (MAX5381), V DD = +2.7V to +5.5V (MAX5382); R L = 10k Ω;
C L = 50pF, T A = T MIN to T MAX , unless otherwise noted. Typical values are T A = +25°C.) (Note 7)
Note 1: Guaranteed from code 5 to code 255.
Note 2: The offset value extrapolated from the range over which the INL is guaranteed.
Note 3: MAX5382 tested at V
DD = +5V ±10%.
Note 4: MAX5380 tested at V DD = +3V ±10%, MAX5381 tested at V DD = 5V ±10%.
Note 5: Actual output voltages at full scale are 255/256 x V
REF
.
Note 6: Output settling time is measured by taking the code from code 5 to 255, and from code 255 to 5.
Note 7: Guaranteed by design.
