AC Electrical Characteristics (Continued)

Note 10: Typical figures are at T

= 25˚C, and represent most likely parametric norms. Test limits are guaranteed to National’s AOQL (Average Outgoing Quality

Level).

Note 11: Integral Non Linearity is defined as the deviation of the analog value, expressed in LSBs, from the straight line that passes through positive and negative

full-scale.

Note 12: Timing specifications are tested at TTL logic levels, V

= 0.4V for a falling edge and V

= 2.4V for a rising edge.

Note 13: Optimum performance will be obtained by keeping the reference input in the 1.8V to 2.2V range. The LM4051CIM3-ADJ (SOT-23 package) is

recommended for this application.

Note 14: I

is the current consumed by the switching of the output drivers and is primarily determined by load capacitance on the output pins, the supply voltage,

, and the rate at which the outputs are switching (which is signal dependent). I

+....C

) where V

is the output driver power supply

voltage, C

is total capacitance on the output pin, and f

is the average frequency at which that pin is toggling.

Note 15: Excludes I

. See note 14.
