converter accuracy.

With the decoded converter described above, a 1%  
change in any of the converter’s switches will affect  
the output by no more than 0.25% of full-scale as  
compared to 0.5% for a conventional converter. In  
other words the conventional D/A converter can be  
made less sensitive to the quality of its individual bits  
by decoding.

settlingtime,andbandwidth.TheDACoutputequiva-  
lent circuit can be represented as shown in Figure 1.  
Digitalfeedthroughisthechangeinanalogoutputdue  
to the toggling conditions on the converter input data  
lines when the analog input VREF is at 0V. The  
SP7514/HS3140verylowCOandthereforewillyield  
low digital feedthrough. Inputs to the DAC can be  
buffered.Thisinputlatchwithmicroprocessorcontrol  
is shown in Figure 4.  
In the SP7514/HS3140 the first four MSB’s are  
decodedinto16levelswhichdrive15equallyweighted  
current sources. The sensitivity of each switch on the  
output is reduced by a factor of 8. Each of the 15  
sources contributes 6.25% output change rather than  
an MSB change of 50% for the common approach.  
SettlingtimeisdirectlyaffectedbyCO.InFigure1,CO  
combines with Rf to add a pole to the open loop  
response, reducing bandwidth and causing excessive  
phase shift - which could result in ringing and/or  
oscillation.Afeedbackcapacitor,Cf mustbeaddedto  
restorestability.EvenwithCf,thereisstillazero-pole  
mismatchduetoRiCO whichiscodedependent. This  
codedependentmismatchisminimizedwhenCORi =  
RfCf. However Cf must now be made larger to  
compensate for worst case ∆RiCO - resulting in re-  
ducedbandwidthandincreasedsettlingtime.Withthe  
SP7514/HS3140, small values for Cf must be used.  
FollowingthedecodedsectionoftheDACastandard  
binary weighted R-2R approach is used. This divides  
each of the 16 levels (or 6.25% of F.S.) into 4096  
discrete levels (the 12 LSB’s).  
Output Capacitance  
The SP7514/HS3140 have very low output capaci-  
tance(CO).ThisisspecifiedbothwithallswitchesON  
andallswitchesOFF.Outputcapacitancevariesfrom  
50pF to 100pF over all input codes. This low capaci-  
tance is due in part to the decoding technique used.  
Smaller switches are used with resulting less capaci-  
tance. Three important system characteristics are  
affected by CO and∆CO; namely digital feedthrough,
