Electrical Characteristics Notes
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 This 500 mW specification applies for all packages The low intrinsic power dissipation of this part (and the fact that there is no way to significantly modify
the power dissipation) removes concern for heat sinking
Note 4 Both I

Note 5 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
zero and full-scale adjustment the plot of the 4096 analog voltage outputs will each be within 0 012%
scale The unit ppm of FSR (parts per million of full-scale range) and ppm of FS (parts per million of full-scale) are used for convenience to define specs of very
small percentage values typical of higher accuracy converters 1 ppm of FSR

Note 10 Typicals are at 25 C and represent the most likely parametric norm
Note 11 Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level)
Note 12 Design limits are guaranteed but not 100% production tested These limits are not used to calculate outgoing quality levels
