Peripheral operating requirements and behaviors
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 < 16 MHz, Max hardware averaging (AVGE = %1, AVGS = %11)
6. Input data is 100 Hz sine wave. ADC conversion clock < 12 MHz.
7. Input data is 1 kHz sine wave. ADC conversion clock < 12 MHz.
