TERMINOLOGY
Relative Accuracy or Integral Nonlinearity (INL)
For the DAC, relative accuracy or INL is a measure of the
maximum deviation, in LSBs, from a straight line passing
through the endpoints of the DAC transfer function. A typical
INL vs. code plot is shown in Figure 7.
Differential Nonlinearity (DNL)
DNL 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 ensures mono-
tonicity. A typical DNL vs. code plot is shown in Figure 10.
Gain Error
Gain error is the difference between the actual and ideal analog
output range, expressed as a percent of the full-scale range.
It is the deviation in slope of the DAC transfer characteristic
from ideal.
Gain Error Temperature Coefficient
Gain error temperature coefficient is a measure of the change
in gain error with changes in temperature. It is expressed in
ppm/°C.
Zero-Code Error
Zero-code error is a measure of the output error when zero
code is loaded to the DAC register.
Zero-Code Temperature Coefficient
This is a measure of the change in zero-code error with a
change in temperature. It is expressed in mV/°C.

Digital-to-Analog Glitch Impulse
Digital-to-analog glitch impulse is the impulse injected into the
analog output when the input code in the DAC register changes
state. It is normally specified as the area of the glitch in nV-sec
and is measured when the digital input code is changed by
1 LSB at the major carry transition. A digital-to-analog glitch
impulse plot is shown in Figure 20.
Digital Feedthrough
Digital feedthrough is a measure of the impulse injected into
the analog output of the DAC from the digital inputs of the
DAC, but it is measured when the DAC output is not updated.
CS
is specified in nV-sec and is measured with a full-scale code
change on the data bus, that is, from all 0s to all 1s and vice
versa. A typical digital feedthrough plot is shown in Figure 19.
Power Supply Rejection Ratio (PSRR)
PSRR indicates how the output of the DAC is affected by changes
in the power supply voltage. The power supply rejection ratio is
quoted in terms of percent change in output per percent change
in V
