34. Based on device characterization (Not production tested).
35. By using switched capacitors at the ADC input an effective input resistance is created. Holding the gain and number of bits constant, the resistance is proportional
Operation in continuous sample mode
fclk = 6.144 MHz
Reference = 1.024 V internal reference bypassed on P3.2 or P0.3
Unless otherwise specified, all charts and graphs show typical values
to the inverse of the clock frequency. This value is calculated, not measured. For more information see the Technical Reference Manual.
