_______________________________________________________________________________________
Note 1: Tested at VDD = +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 300VP-P. An external reference below 2.5V can com-
promise the ADC performance.
TIMING CHARACTERISTICS (Figure 1)
(VDD = 2.7V to 3.6V, VREF = 2.5V, fDCLK = 2MHz (50% duty cycle), fSAMPLE = 125kHz, 12-bit mode, 0.1F capacitor at REF, TA =
TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
