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 6 Design limits are guaranteed but not 100% tested These limits are not used to calculate outgoing quality levels Guaranteed for V
and V
Note 7 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
performing a zero and full-scale adjustment the plot of the 4096 analog voltage outputs will each be within 0 012%
zero and full-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 In this instance 1 ppm of FSR

Note 8 This spec implies that all parts are guaranteed to operate with a write pulse or transfer pulse width (t
100 ns The entire write pulse must occur within the valid data interval for the specified t
Note 9 To achieve this low feedthrough in the D package the user must ground the metal lid If the lid is left floating the feedthrough is typically 6 mV
Note 10 Typicals are at 25 C and represent the most likely parametric norm
