Notes:
1. An additional two F CLK cycles are required to start and complete a conversion.
2. Additional tracking time may be required depending on the output impedance connected to the ADC input.
3. Represents one standard deviation from the mean.
4. Includes ADC offset, gain, and linearity variations.
