GENERAL DESCRIPTION  
ORDERING GUIDE1  
The AD7528 is a monolithic dual 8-bit digital/analog converter  
featuring excellent DAC-to-DAC matching. It is available in  
skinny 0.3" wide 20-lead DIPs and in 20-lead surface mount  
packages.

Data is transferred into either of the two DAC data latches via a  
common 8-bit TTL/CMOS compatible input port. Control  
input DAC A/DAC B determines which DAC is to be loaded.  
The AD7528’s load cycle is similar to the write cycle of a ran-  
dom access memory and the device is bus compatible with most  
8-bit microprocessors, including 6800, 8080, 8085, Z80.

The device operates from a +5 V to +15 V power supply, dis-  
sipating only 20 mW of power.  
±4 LSB Q-20  
Both DACs offer excellent four quadrant multiplication charac-  
teristics with a separate reference input and feedback resistor for  
each DAC.  
NOTES  
1Analog Devices reserves the right to ship side-brazed ceramic in lieu of cerdip. Parts  
will be marked with cerdip designator “Q.”  
2Processing to MIL-STD-883C, Class B is available. To order, add suffix “/883B” to  
part number. For further information, see Analog Devices’ 1990 Military Products  
Databook.  
PRODUCT HIGHLIGHTS  
1. DAC-to-DAC matching: since both of the AD7528 DACs are  
fabricated at the same time on the same chip, precise match-  
ing and tracking between DAC A and DAC B is inherent.  
The AD7528’s matched CMOS DACs make a whole new  
range of applications circuits possible, particularly in the  
audio, graphics and process control areas.  
3N = Plastic DIP; P = Plastic Leaded Chip Carrier; Q = Cerdip; R = SOIC.  
2. Small package size: combining the inputs to the on-chip DAC  
latches into a common data bus and adding a DAC A/DAC B  
select line has allowed the AD7528 to be packaged in either a  
small 20-lead DIP, SOIC or PLCC.
