SPECIFICATION DEFINITIONS

Linearity Error

The deviation of a code from a straight line which connects the two endpoints of the A/D

Converter transfer function. One endpoint is located 1/2 LSB below the first code transition

and the other endpoint 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+) - (VREF-)} - 3/2 LSB].

Units are in LSBs.

Unipolar Offset

The deviation of the first code transition from the ideal (1/2 LSB above the voltage on the

AIN- pin.). When in unipolar mode (U/B bit = 1). 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). When in bipolar mode (U/B bit = 0). Units are in LSBs.
