2. SAR ADC performance is not guaranteed when IRC is used as clock source for PLL0 to generate SAR ADC clock.
3. AD_CK clock is always half of the ADC module input clock defined via the auxiliary clock divider for the ADC.
4. During the sample time the input capacitance C

S

 can be charged/discharged by the external source. The internal

resistance of the analog source must allow the capacitance to reach its final voltage level within t

sample

. After the end of the

sample time t

sample

, changes of the analog input voltage have no effect on the conversion result. Values for the sample

clock t

sample

 depend on programming.

5. This parameter does not include the sample time t

sample

, but only the time for determining the digital result and the time to

load the result register with the conversion result.

6. See the above figure.
7. Subject to change with additional -40°C characterization on final silicon version.
8. Below 4.5V, ENOB - 9.5b, THD- 60dB at Fin= 125KHz
9. Band gap reference only applies to Cut 2 silicon.
10. Minimum and maximum values are t/-3%

NOTE

• For spec complaint operation, do not expose clock sources,

including crystal oscillator, IRC, PLL0, and PLL1 on the
CLKOUT pads while the SAR ADC is converting.

• The ADC performance specifications are not guaranteed if

two or more ADCs simultaneously sample the same shared
channel.

11.3 S/D ADC

The SD ADCs are Sigma Delta 16-bit analog-to-digital converters with 333 Ksps
maximum output rate.
