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.

package, this number increases to 100˚C/W and for the V package this number is 120˚C/W.

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 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

straight line which passes through zero and full scale.

Note 9: Boldface tested limits apply to the LJ and LCJ suffix parts only.

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

Ω resistor.
