LVDS Electrical Characteristics
Note 7: The inputs are protected as shown below. Input voltage magnitudes above V
(Note 3). However, errors in the A/D conversion can occur if the input goes above V
input voltage must be ≤+3.4V to ensure accurate conversions.

Note 11: 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.
Note 12: Timing specifications are tested at TTL logic levels, V
Note 13: Optimum performance will be obtained by keeping the reference input in the 0.8V to 1.2V range. The LM4051CIM3-ADJ (SOT-23 package) is
recommended for external reference applications.
