Note 1:
Total unadjusted error includes offset, full-scale, and linearity errors.
Note 2:
Specified with no external load unless otherwise noted.
Note 3:
Temperature drift is defined as change in output voltage from +25°C to T
MIN
or T
MAX
divided by (25 - T
MIN
) or (T
MAX
- 25).
Note 4:
Guaranteed by design.
Note 5:
All input control signals are specified with t
R
= t
F
= 20ns (10% to 90% of +5V) and timed from a 1.6V voltage level.
Note 6:
Measured with load circuits of Figure 1 and defined as the time required for an output to cross 0.8V or 2.4V.
Note 7:
Defined as the time required for the data lines to change 0.5V when loaded with the circuits of Figure 2.
