TIMING CHARACTERISTICS (Figures 5 and 6) (continued)
(AV
Note 1: Tested at AV
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the gain error and offset
Note 3: Offset nullified.
Note 4: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle. Includes
Note 5: Acquisition time is 5 clock cycles in short acquisition mode and 13 clock cycles in long acquisition mode.
Note 6: Performance is limited by the converter’s noise floor, typically 300µV
Note 7: When an external reference has a different voltage than the specified typical value, the full scale of the ADC scales propor-
Note 8: Defined as the change in positive full scale caused by a ±5% variation in the nominal supply voltage.
