1. All accuracy numbers assume the ADC is calibrated with VREFH = VDDA
2. Typical values assume VDDA = 3.0 V, Temp = 25°C, fADCK = 2.0 MHz unless otherwise stated. Typical values are for
reference only and are not tested in production.
3. The ADC supply current depends on the ADC conversion clock speed, conversion rate and the ADLPC bit (low power).
For lowest power operation the ADLPC bit should be set, the HSC bit should be clear with 1MHz ADC conversion clock
speed.
4. 1 LSB = (VREFH - VREFL)/2N
5. Input data is 1 kHz sine wave.
