Notes:
1. Represents one standard deviation from the mean. Offset and full-scale error can be removed through
2. An additional 2 FCLK cycles are required to start and complete a conversion
3. Additional tracking time may be required depending on the output impedance connected to the ADC input.
4. An increase in tracking time will decrease the ADC throughput.
