Rainbow Electronics MX7828 - Manual (Page 3)

ELECTRICAL CHARACTERISTICS
(V DD = +5V, V REF + = +5V, V REF - = GND, Mode 0, T A = T MIN to T MAX , unless otherwise noted.)
TIMING CHARACTERISTICS (Note 5)
(V DD = +5V, V REF + = +5V, V REF - = GND, Mode 0, T A = T MIN to T MAX , unless otherwise noted.)
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.
