Note 7:
Bipolar zero error is the offset voltage measured from –0.5LSB may cause permanent damage to the device. Exposure to any Absolute when the output code flickers between 0000 0000 0000 0000 and 1111 Maximum Rating condition for extended periods may affect device 1111 1111 1111. Bipolar full-scale error is the worst-case of –FS or +FS reliability and lifetime. untrimmed deviation from ideal first and last code transitions and includes

Guaranteed by design.
Note 5:
Recommended operating conditions.
Note 11:
Temperature coefficient is calculated by dividing the maximum

Integral nonlinearity is defined as the deviation of a code from a change in output voltage by the specified temperature range. straight line passing through the actual endpoints of the transfer curve. The deviation is measured from the center of the quantization band. 4V tWIDTH 0.5V t t 50% 50% DELAY DELAY 239216 F01 4V 4V 0.5V 0.5V
