A.3.3
MC68HC05X16
(1) Performance verified down to 2.5V VR, but accuracy is tested and guaranteed at VR = 5V 10%.
(2) Source impedances greater than 10k will adversely affect internal 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
