Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
Integral nonlinearity is defi ned as the deviation of a code from a may cause permanent damage to the device. Exposure to any Absolute “best fi t straight line” to the transfer curve. The deviation is measured from Maximum Rating condition for extended periods may affect device the center of the quantization band. reliability and lifetime.
