CC2510Fx / CC2511Fx
6.10 7 - 12 bit ADC
TA = 25°C, VDD = 3.0V if nothing else stated. The numbers given here are based on tests performed
in accordance with IEEE Std 1241-2000 [7]. The ADC data are from CC2430 characterization. As the
CC2510x/C2511Fx uses the same ADC, the numbers listed in Table 18 should be good indicators of the
performance to be expected from CC2510x and CC2511x. Note that these numbers will apply for 24 MHz
operated systems (like CC2510x using a 24 MHz crystal or CC2511x using a 48 MHz crystal).
Performance will be slightly different for other crystal frequencies (e.g. 26 MHz and 27 MHz).
