GENERAL D ESCRIP TIO N  
T he high speed parallel data interface connects to the fastest  
processors without wait states. T he double-buffered input struc-  
ture allows the user to load the input registers one at a time,  
then a single load strobe tied to both LDA + LDB inputs will  
update both DAC outputs simultaneously. LDA and LDB can  
also be activated independently to immediately update their re-  
spective DAC registers. An address input decodes DAC A or  
DAC B when the chip select CS input is strobed. An asynchro-  
nous reset input sets the output to zero scale. T he MSB bit can  
be used to establish a preset to midscale when the reset input is  
strobed.  
T he AD8582 is a complete, parallel input, dual 12-bit, voltage  
output DAC designed to operate from a single +5 volt supply.  
Built using a CBCMOS process, this monolithic DAC offers the  
user low cost, and ease-of-use in +5 volt only systems.  
Included on the chip, in addition to the DACs, are a rail-to-rail  
amplifier, latch and reference. T he reference (VREF) is trimmed  
to 2.5 volts output, and the on-chip amplifier gains up the DAC  
output to 4.095 volts full scale. T he user needs only supply a +5  
volt supply.  
T he AD8582 is coded natural binary. T he op amp output  
swings from 0 volt to +4.095 volts for a one-millivolt-per-bit  
resolution, and is capable of driving ±5 mA. Operation down to  
4.3 V is possible with output load currents less than 1 mA.  
T he AD8582 is available in the 24-pin plastic DIP and the sur-  
face mount SOIC-24. Each part is fully specified for operation  
over –40°C to +85°C, and the full +5 V ± 5% power supply  
range.
