1.V_DD = 5.0 Vdc ± 0.5v, V_SS = 0 Vdc, V_DDA/V_DDAREF = 5.0 Vdc ± 0.5v, V_SSA = 0 Vdc, V_REFH = 5.0 Vdc ± 0.5v
2.Source impedances greater than 10 kΩ adversely affect internal RC charging time during input sampling.
3.The external system error caused by input leakage current is approximately equal to the product of R
source and input current.
