Free Dynamic Range will generally be much better due to  
the harmonics falling outside the passband. Even with a  
bandpass filter, updating the DAC at greater than 4 times per  
cycle will (1) minimize the 2nd and 3rd harmonic magni-  
tudes by having the output slew excessively between any  
successive clock and (2) will keep the (fCLK – 2fO) spur and  
other even order spurs from folding back close to the  
fundamental under the condition fOUT = 1/3fCLK and (3) will  
keep the (fCLK – 3fO) spur and other spurs from folding back  
EVALUATION BOARD  
The high frequency signals used in operating the DAC650  
can cause difficult layout problems. It is especially difficult  
to build a high-performance prototype board using the  
DAC650. It is recommended that an evaluation fixture be  
used for prototyping. An evaluation fixture includes a  
DAC650 soldered to the PC board. Both grades are available  
for the evaluation fixture.  
ORDERING INFORMATION  
close to the fundamental under the condition fOUT = 1/4fCLK  
.
MODEL  
DESCRIPTION  
Making use of the high update rate of the DAC650 helps to  
lessen the problems of harmonics “folding back” into the  
passband.
