DEFINITION OF TERMS
Linearity Error
This is the maximum deviation of any code from a straight line
passing through the endpoints of the transfer function. The
endpoints of the transfer function are zero scale (not to be
confused with bipolar zero), a point 0.5 LSB below the first
code transition (000 . . . 000 to 000 . . . 001) and full scale, a
point 1.5 LSB above the last code transition (111 . . . 110 to
111 . . . 111). The error is expressed as a percentage of full scale.
Differential Linearity Error
This is the difference between any code’s actual width and the
ideal (1 LSB) width. Differential linearity error is expressed in
LSBs. A differential linearity specification of
± 1 LSB or less
guarantees monotonicity.
Positive Full-Scale Error
Positive full-scale error is the deviation of the last code transition
(111 . . . 110 to 111 . . . 111) from the ideal (VREF
±3/2 LSBs).
It applies to both positive and negative analog input ranges and
is expressed in microvolts.
Unipolar Offset Error
Unipolar offset error is the deviation of the first code transition
from the ideal (AGND + 0.5 LSB) when operating in the Uni-
polar mode. It is expressed in microvolts.
Bipolar Zero Error
This is the deviation of the midscale transition (0111 . . . 111 to
1000 . . . 000) from the ideal (AGND – 0.5 LSB) when operating
in the Bipolar mode. It is expressed in microvolts.
Bipolar Negative Full-Scale Error
This is the deviation of the first code transition from the ideal
(–VREF + 0.5 LSB) when operating in the Bipolar mode. It is
expressed in microvolts.
Positive Full-Scale Overrange
Positive full-scale overrange is the amount of overhead available
to handle input voltages greater than +VREF (for example, noise
peaks or excess voltages due to system gain errors in system
calibration routines) without introducing errors due to overloading
the analog modulator or overflowing the digital filter. It is
expressed in millivolts.
Negative Full-Scale Overrange
This is the amount of overhead available to handle voltages below
–VREF without overloading the analog modulator or overflowing
the digital filter. Note that the analog input will accept negative
voltage peaks even in the Unipolar mode. The overhead is
expressed in millivolts.
