DEFINITIONS
Differential Nonlinearity (DNL): The difference between
the measured change and the ideal 1LSB change for any
two adjacent codes. The DNL error between any two codes
is calculated as follows:
Where ΔV
two adjacent codes.
Digital Feedthrough: The glitch that appears at the ana-
log output caused by AC coupling from the digital inputs
when they change state. The area of the glitch is specifi ed
in (nV)(sec).
Full-Scale Error (FSE): The deviation of the actual full-scale
voltage from ideal. FSE includes the effects of offset and
gain errors (see Applications Information).
Integral Nonlinearity (INL): The deviation from a straight
line passing through the endpoints of the DAC transfer
curve (Endpoint INL). Because the output cannot go
below zero, the linearity is measured between full scale
and the lowest code that guarantees the output will be

Voltage Offset Error (V
output when the DAC is loaded with all zeros. A single
supply DAC can have a true negative offset, but the output
cannot go below zero (see Applications Information).
For this reason, single supply DAC offset is measured at
the lowest code that guarantees the output will be greater
than zero.
