1. Typical values assume VDDA = 5.0 V, Temp = 25 °C, fADCK=1.0 MHz unless otherwise stated. Typical values are for
reference only and are not tested in production.
2. 1 LSB = (VREFH - VREFL)/2N
3. Monotonicity and no-missing-codes guaranteed in 10-bit and 8-bit modes
4. VADIN = VDDA
5. IIn = leakage current (refer to DC characteristics)
