DEFINITIONS OF SPECIFICATIONS  
Temperature Drift  
Linearity Error (Also Called Integral Nonlinearity or INL)  
Linearity error is defined as the maximum deviation of the  
actual analog output from the ideal output, determined by a  
straight line drawn from zero to full scale.  
Temperature drift is specified as the maximum change from the  
ambient (+25°C) value to the value at either TMIN or TMAX. For  
offset and gain drift, the drift is reported in ppm of full-scale  
range (FSR) per degree C. For reference drift, the drift is  
reported in ppm per degree C.  
Differential Nonlinearity (or DNL)  
DNL is the measure of the variation in analog value, normalized  
to full scale, associated with a 1 LSB change in digital input  
code.  
Power Supply Rejection  
The maximum change in the full-scale output as the supplies  
are varied from nominal to minimum and maximum specified  
voltages.  
Monotonicity  
A D/A converter is monotonic if the output either increases or  
remains constant as the digital input increases.  
Settling Time  
The time required for the output to reach and remain within a  
specified error band about its final value, measured from the  
start of the output transition.  
Offset Error  
The deviation of the output current from the ideal of zero is  
called offset error. For IOUTA, 0 mA output is expected when the  
inputs are all 0s. For IOUTB, 0 mA output is expected when all  
inputs are set to 1s.  
Glitch Impulse  
Asymmetrical switching times in a DAC give rise to undesired  
output transients that are quantified by a glitch impulse. It is  
specified as the net area of the glitch in pV-s.  
Gain Error  
The difference between the actual and ideal output span. The  
actual span is determined by the output when all inputs are set  
to 1s minus the output when all inputs are set to 0s.  
Spurious-Free Dynamic Range  
The difference, in dB, between the rms amplitude of the output  
signal and the peak spurious signal over the specified bandwidth.  
Output Compliance Range  
Total Harmonic Distortion  
The range of allowable voltage at the output of a current-output  
DAC. Operation beyond the maximum compliance limits may  
cause either output stage saturation or breakdown resulting in  
nonlinear performance.  
THD is the ratio of the rms sum of the first six harmonic  
components to the rms value of the measured output signal. It is  
expressed as a percentage or in decibels (dB).
