Note 1:
Tested at V
DD
= +2.7V.
Note 2:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
been calibrated.
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:
Resistance measured from the source to drain of the switch.
Note 6:
ADC performance is limited by the conversion noise floor, typically 300μV
P-P
. An external reference below 2.5V can com-
promise the ADC performance.
