ELECTRICAL CHARACTERISTICS Note 6:
Dynamic specifications are guaranteed for dual supply operation
Note 8:
Bipolar offset is the offset voltage measured from –0.5LSB with a single-ended + AIN input and – AIN grounded. For single supply when the output code flickers between 0000 0000 0000 and dynamic specifications, refer to the Typical Performance Characteristics. 1111 1111 1111.
Note 7:
Integral nonlinearity is defined as the deviation of a code from a
Note 9:
Guaranteed by design, not subject to test. straight line passing through the actual endpoints of the transfer curve.
Note 10:
Recommended operating conditions. The deviation is measured from the center of the quantization band.
