Note 10:
Typical figures are at T

= 25C, and represent most likely parametric norms. Test limits are guaranteed to National’sAOQL(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
IL
= 0.4V for a falling edge and V
IH
= 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
DR
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,
V
