(1) Performance verified down to 2.5V ∆VR, but accuracy is tested and guaranteed at ∆VR = 5V±10%.
(2) Source impedances greater than 10kΩ 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
