1. Typical values assume V_DDA = 5.0 V, Temp = 25°C, f_ADCK=1.0 MHz unless otherwise stated. Typical values are for
reference only and are not tested in production.
2. Includes quantization
3. 1 LSB = (V_REFH - V_REFL)/2^N
4. Monotonicity and no-missing-codes guaranteed in 10-bit and 8-bit modes
5. V_ADIN = V_SSA
6. V_ADIN = V_DDA
7. I_In = leakage current (refer to DC characteristics)
