TIMING CHARACTERISTICS (Figures 5 and 6)
(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 nulled.
Note 4: Conversion time is defined as the number of clock cycles multiplied by the clock period, clock has 50% duty cycle.
Note 5: ADC performance is limited by the converter’s noise floor, typically 300µVp-p.
Note 6 When an external reference has a different voltage than the specified typical value, the full scale of the ADC will scale
Note 7: Electrical characteristics are guaranteed from AV
Note 8: Defined as the change in positive full-scale caused by a ±5% variation in the nominal supply voltage.
