Timing Diagram
AC FEEDTHROUGH ERROR
This is the error caused by capacitance coupling from VREF to
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.
PARAMETER DEFINITIONS
RESOLUTION
Resolution is the number of states (2
n) that the full-scale range
(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 VREF –1 LSB.
OUTPUT CAPACITANCE
Output Capacitance is that capacitance between IOUT 1A, IOUT 1B,
IOUT 1C, or IOUT 1D and AGND.
