Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
Integral nonlinearity is defined as the deviation of a code from a may cause permanent damage to the device. Exposure to any Absolute straight line passing through the actual endpoints of the transfer curve. The Maximum Rating condition for extended periods may affect device deviation is measured from the center of the quantization band. reliability and lifetime.
Note 6:
Offset error is the offset voltage measured from –0.5 LSB when the
