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 the ground pins.

Note 4: Total unadjusted error includes offset, full-scale, and linearity.

can cause this input diode to conduct, especially at elevated temperatures, and cause errors for analog inputs near full-scale. The spec allows 50 mV forward bias

Note 6: Typicals are at 25˚C and represent most likely parametric norm.

Note 7: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).

Note 8: Design limits are guaranteed but not 100% production tested. These limits are not used to calculate outgoing quality levels.

Note 9: The temperature coefficient is 0.3%/˚C.

Note 10: Human body model, 100 pF discharged through 1.5 k

Ω resistor.
