4. SPECIFICATION DEFINITIONS

Linearity Error

The deviation of a code from a straight line which connects the two end points of the A/D Converter

transfer function. One end point is located 1/2 LSB below the first code transition and the other end

point is located 1/2 LSB beyond the code transition to all ones. Units in percent of full-scale.

Differential Nonlinearity

The deviation of a code's width from the ideal width. Units in LSBs.

Full Scale Error

The deviation of the last code transition from the ideal [{(VREF) - (V-)} - 3/2 LSB]. Units are in LSBs.

Bipolar Offset

The deviation of the mid-scale transition (111...111 to 000...000) from the ideal (1/2 LSB below the

voltage on the AIN- pin). Units are in LSBs.LK
