Input voltage magnitudes above VA or below GND will not damage this device, provided current is limited per (). However, errors in the A/D conversion can occur if the input goes above VA or below GND by more than 100 mV. As an example, if VA is 4.75V, the full-scale input voltage must be ≤4.85V to ensure accurate (2) To guarantee accuracy, it is required that |VA–VD| ≤ 100 mV and separate bypass capacitors are used at each power supply pin. (3) With the test condition for VREF = +2.0V (4VP-P differential input), the 12-bit LSB is 977 µV. (4) Typical figures are at TA = TJ = 25°C, and represent most likely parametric norms. Test limits are guaranteed to National's AOQL (Average Outgoing Quality Level). (5) Integral Non Linearity is defined as the deviation of the analog value, expressed in LSBs, from the straight line that passes through positive and negative full-scale.
