Freescale Semiconductor
Preliminary
1. INL measured from V
2. LSB = Least Significant Bit
3. ADC clock cycles
4. Assumes each voltage reference pin is bypassed with 0.1μF ceramic capacitors to ground
5. The current that can be injected or sourced from an unselected ADC signal input without impacting the performance of
6. Absolute error includes the effects of both gain error and offset error.
7. Please see the 56F8300 Peripheral User’s Manual for additional information on ADC calibration.
