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. Maximum Rating condition for extended periods may affect device The 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

All voltage values are with respect to ground with GND and OGND the output code flickers between 0000 0000 0000 and 1111 1111 1111. wired together (unless otherwise noted).
Note 7:
Guaranteed by design, not subject to test.
