TERMINOLOGY
Total Unadjusted Error
Total unadjusted error is a comprehensive specification that
includes full-scale error, relative accuracy, and zero code error.
Maximum output voltage is VREF 1 LSB (ideal), where 1 LSB
(ideal) is VREF/256. The LSB size varies over the VREF range.
Therefore, the zero code error, relative to the LSB size, increases
as VREF decreases. Accordingly, the total unadjusted error, which
includes the zero code error, also varies in terms of LSB over the
VREF range. As a result, total unadjusted error is specified for a
fixed reference voltage of 10 V.
Relative Accuracy
Relative accuracy or endpoint nonlinearity is a measure of the
maximum deviation from a straight line passing through the
endpoints of the DAC transfer function. It is measured after
allowing for zero code error and full-scale error and is normally
expressed in LSB or as a percentage of full-scale reading.
Differential Nonlinearity
Differential nonlinearity is the difference between the measured
change and the ideal 1 LSB change between any two adjacent
codes. A specified differential nonlinearity of ±1 LSB maximum
over the operating temperature range ensures monotonicity.
Digital Feedthrough
Digital feedthrough is the glitch impulse transferred to the
output of the DAC due to a change in its digital input code. It is
specified in nV sec and is measured at VREF = 0 V.
Digital Crosstalk
Digital crosstalk is the glitch impulse transferred to the output
of one converter (not addressed) due to a change in the digital
input code to another addressed converter. It is specified in nV
sec and is measured at VREF = 0 V.
AC Feedthrough
AC feedthrough is the proportion of reference input signal that
appears at the output of a converter when that DAC is loaded
with all 0s.
Channel-to-Channel Isolation
Channel-to-channel isolation is the proportion of input signal
from the reference of one DAC (loaded with all 1s) that appears
at the output of one of the other three DACs (loaded with all 0s)
The figure given is the worst case for the three other outputs
and is expressed as a ratio in dB.
Full-Scale Error
Full-scale error is defined as
FSE = Measured Value Zero Code Error Ideal Value
