Analog
1. All accuracy numbers assume the ADC is calibrated with V
2. Typical values assume V
3. The ADC supply current depends on the ADC conversion clock speed, conversion rate and the ADLPC bit (low power).
4. 1 LSB = (V
5. ADC conversion clock <16MHz, Max hardware averaging (AVGE = %1, AVGS = %11)
6. Input data is 100 Hz sine wave. ADC conversion clock <12MHz.
7. Input data is 1 kHz sine wave. ADC conversion clock <12MHz.

For lowest power operation the ADLPC bit should be set, the HSC bit should be clear with 1MHz ADC conversion clock
