ELECTRICAL CHARACTERISTICS

(VDD = +5V, VREF+ = +5V, VREF- = GND, Mode 0, TA = TMIN to TMAX, unless otherwise noted.)

TIMING CHARACTERISTICS (Note 5)

(VDD = +5V, VREF+ = +5V, VREF- = GND, Mode 0, TA = TMIN to TMAX, 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 TMIN or TMAX divided by (25 - TMIN) or (TMAX - 25).

Note 4: Guaranteed by design.

Note 5: All input control signals are specified with tR = tF = 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.
