III. Timing and Oscillation

️· Master Clock Frequency Range (MCLK): 1 MHz to 16.384 MHz
️· AMCLK: Controlled by prescaler settings.

IV. Performance/Accuracy (at standard conditions, unless otherwise noted)

️· Operating Conditions: -40°C to +85°C (Temperature)
️· Input Offset: Dependent on PGA gain setting (refer to Figure 2-19 of the full datasheet for details)
️· Signal-to-Noise Ratio (SNR): (Not explicitly provided in these excerpts, but a key performance metric to review in the full datasheet.)
️· Dynamic Range: (Not explicitly provided. Consult the full datasheet.)
️· Integral Nonlinearity (INL): (Not explicitly provided. Consult the full datasheet.)
️· Differential Nonlinearity (DNL): (Not explicitly provided. Consult the full datasheet.)

Important Notes/Context from the Datasheet Excerpts

️· BOOST Setting: The "BOOST" setting (BOOST<1:0>) affects the analog operating current (AIDD). BOOST=00 represents a standard configuration, while BOOST=11 enables an alternative configuration with potentially different performance characteristics.
️· Shutdown Mode: Shutdown mode significantly reduces power consumption, but at the expense of the ADC being inactive.
️· Clocking: The MCLK frequency is crucial for ADC performance. The full datasheet will provide guidance on selecting appropriate clock frequencies for the specific application.
️· Accuracy Specifications: The provided excerpts list some key performance characteristics, but for a complete understanding of the ADC's accuracy, you'll need to consult the full datasheet, which contains more detailed specifications and test conditions.
