Note 1: DC accuracy is tested at VAVDD = +5.0V and VDVDD = +3.0V. Performance at power-supply tolerance limits is guaranteed
by power-supply rejection test.
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range and
offset have been calibrated.
Note 3: Offset nullified.
Note 4: One sample is achieved every 18 clocks in continuous conversion mode:
Note 5: The track/hold acquisition time is two SCL cycles as illustrated in Figure 11:
Note 6: A filter on SDA and SCL delays the sampling instant and suppresses noise spikes less than 10ns in high-speed mode and
50ns in fast mode.
Note 7: ADC performance is limited by the converter’s noise floor, typically 225μVP-P.
