1. All accuracy numbers assume the ADC is calibrated with V_REFH = V_DDA
a 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.

1. Typical values assume V_DDA = 3.0 V, Temp = 25°C, f_ADCK = 6 MHz unless otherwise stated. Typical values are for
reference only and are not tested in production.
2. ADC must be configured to use the internal voltage reference (VREFOUT)
3. PGA reference connected to the VREFOUT pin. If the user wishes to drive VREFOUT with a voltage other than the output
of the VREF module, the VREF module must be disabled.
