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.

(6)

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.
