DIGITAL FEEDTHROUGH  
TERMINOLOGY  
Digital Feedthrough is a measure of the impulse injected into  
the analog output of a DAC from the digital inputs of the same  
DAC, but is measured when the DAC is not updated. It is  
specified in nV-s and measured with a full-scale code change on  
the data bus, i.e., from all 0s to all 1s and vice versa.  
INTEGRAL NONLINEARITY  
For the DACs, relative accuracy or endpoint nonlinearity is a  
measure of the maximum deviation, in LSBs, from a straight  
line passing through the endpoints of the DAC transfer function.  
A graphical representation of the transfer curve is shown in  
Figure 14.  
DIGITAL CROSSTALK  
Digital Crosstalk is the glitch impulse transferred to the output  
of one converter due to a digital code change to another DAC.  
It is specified in nV-s.  
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  
ensures monotonicity.  
ANALOG CROSSTALK  
Analog Crosstalk is a change in output of any DAC in response  
to a change in the output of the other DAC. It is measured in  
LSBs.  
ZERO CODE ERROR  
Zero Code Error is the measured output voltage from VOUT of  
either DAC when zero code (all zeros) is loaded to the DAC  
latch. It is due to a combination of the offset errors in the DAC  
and output amplifier. Zero scale error is expressed in LSBs.  
POWER SUPPLY REJECTION RATIO (PSRR)  
This specification indicates how the output of the DAC is  
affected by changes in the power supply voltage. Power supply  
rejection ratio is quoted in terms of % change in output per %  
change in VDD for full-scale output of the DAC. VDD is varied  
±10%.  
GAIN ERROR  
This is a measure of the span error of the DAC. It is the deviation  
in slope of the DAC transfer characteristic from ideal, expressed  
as a percent of the full-scale value. It includes full-scale errors  
but not offset errors.  
DIGITAL-TO-ANALOG GLITCH IMPULSE  
Digital-to-Analog Glitch Impulse is the impulse injected into the  
analog output when the digital inputs change state with the  
DAC selected and the LDAC used to update the DAC. It is  
normally specified as the area of the glitch in nV-s and is  
measured when the digital input code is changed by 1 LSB at  
the major carry transition.
