Electrical Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions.
Note 2: All voltages are measured with respect to GND, unless otherwise specified.
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by T
allowable power dissipation at any temperature is P

package, this number increases to 100˚C/W and for the V package this number is 120˚C/W.
Note 4: For current switching applications, both I

Note 5: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 6: Guaranteed, but not 100% production tested. These limits are not used to calculate outgoing quality levels.
Note 7: Guaranteed at V
Note 8: The unit “FSR” stands for “Full Scale Range.” “Linearity Error” and “Power Supply Rejection” specs are based on this unit to eliminate dependence on a
particular V
that after performing a zero and full scale adjustment (see Sections 2.5 and 2.6), the plot of the 256 analog voltage outputs will each be within 0.05%xV
Note 11: The entire write pulse must occur within the valid data interval for the specified t
Note 12: Typicals are at 25˚C and represent most likely parametric norm.
Note 13: Human body model, 100 pF discharged through a 1.5 k
straight line which passes through zero and full scale.
Note 9: Boldface tested limits apply to the LJ and LCJ suffix parts only.
