1. All accuracy numbers assume the ADC is calibrated with V

= V
DDA
2. The ADC supply current depends on the ADC conversion clock speed, conversion rate and ADC_CFG1[ADLPC] (low
power). For lowest power operation, ADC_CFG1[ADLPC] must be set, the ADC_CFG2[ADHSC] bit must be clear with 1
MHz ADC conversion clock speed.

4. ADC conversion clock < 16 MHz, Max hardware averaging (AVGE = %1, AVGS = %11)
5. Input data is 1 kHz sine wave. ADC conversion clock < 12 MHz.
6. ADC conversion clock < 3 MHz
