PARAMETER DEFINITIONS
RESOLUTION
Resolution is the number of states (2
(FSR) of a DAC is divided (or resolved) into.
NONLINEARITY
Nonlinearity (Relative Accuracy) is a measure of the maximum
deviation from a straight line passing through the end-points of
the DAC transfer function. It is measured after adjusting for
ideal zero and full-scale and is expressed in LSB, %, or ppm of
full-scale range.
DIFFERENTIAL NONLINEARITY
Differential Nonlinearity is the worst case deviation of any adja-
cent analog outputs from the ideal 1 LSB step size. A specified
differential nonlinearity of 1 LSB maximum over the operating
temperature range ensures monotonicity.
GAIN ERROR
Gain Error (full-scale error) is a measure of the output error be-
tween the ideal and actual DAC output. The ideal full-scale
output is V

AC FEEDTHROUGH ERROR
This is the error caused by capacitance coupling from V
the DAC output with all switches off.
SETTLING TIME
Settling Time is the time required for the output function of the
DAC to settle to within 1/2 LSB for a given digital input signal.
PROPAGATION DELAY
This is a measure of the internal delays of the DAC. It is defined
as the time from a digital input change to the analog output cur-
rent reaching 90% of its final value.
CHANNEL-TO-CHANNEL ISOLATION
This is the portion of input signal that appears at the output of a
DAC from another DAC’s reference input. It is expressed as a
ratio in dB.
DIGITAL CROSSTALK
Digital Crosstalk is the glitch energy transferred to the output of
one DAC due to a change in digital input code from other
DACs. It is specified in nVs.
