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.
4.When subjected to a Human Body Model (HBM) ESD event as specified in AEC Q100-002 these pins may exhibit
recoverable leakage values within the specification indicated.
