Typical Operating Characteristics
(VDD = +3V, VREF = +2.5V, fSCLK = 4.8MHz, CLOAD = 30pF, TA = +25°C, unless otherwise noted.)
Note 10: This time is defined as the number of clock cycles needed for conversion multiplied by the clock period. If the internal ref
erence needs to be powered up, the total time is additive. The internal reference is always used for temperature measure
ments.
