Note 1: Stresses beyond those listed under Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to any Absolute  
Maximum Rating condition for extended periods may effect device  
reliability and lifetime.  
Note 7: Bipolar zero-scale error is the offset voltage measured from  
–0.5LSB when the output code flickers between 0000 0000 0000 0000 0000  
and 1111 1111 1111 1111 1111. Full-scale bipolar error is the worst-case  
of –FS or +FS untrimmed deviation from ideal first and last code transitions  
and includes the effect of offset error.  
Note 2: All voltage values are with respect to ground.  
Note 8: All specifications in dB are referred to a full-scale 5V input with a  
5V reference voltage.  
Note 3: When these pin voltages are taken below ground or above REFor  
OV , they will be clamped by internal diodes. This product can handle  
DD  
input currents up to 100mA below ground or above REFor OV without  
latch-up.

Note 6: Integral nonlinearity is defined as the deviation of a code from a  
straight line passing through the actual endpoints of the transfer curve.  
The deviation is measured from the center of the quantization band.
