Note 5: Guaranteed by design, not subject to test.
Note 6: Integral nonlinearity is defined as the deviation of a code from
a straight line passing through the actual endpoints of the transfer
curve. The deviation is measured from the center of the quantization
band.

(external oscillator).
Note 8: The converter is in external SCK mode of operation such that
the SCK pin is used as digital input. The frequency of the clock signal
driving SCK during the data output is f
Note 9: The converter is in internal SCK mode of operation such that
the SCK pin is used as digital output.
Note 10: The external oscillator is connected to the F
oscillator frequency, f
Note 11: The converter uses the internal oscillator. F
Note 12: The output noise includes the contribution of the internal
calibration operations.
Note 13: Guaranteed by design and test correlation.
