4. SPECIFICATION DEFINITIONS
Linearity Error
The deviation of a code from a straight line which connects the two endpoints of the ADC
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.
