GENERAL DESCRIPTION  
Both parts are offered in the same pinout, allowing users to  
The AD7396/AD7397 series of dual, 12-bit and 10-bit voltage-  
output digital-to-analog converters are designed to operate from  
a single +3 V supply. Built using a CBCMOS process, these  
monolithic DACs offer the user low cost and ease of use in  
single supply +3 V systems. Operation is guaranteed over the  
supply voltage range of +2.7 V to +5.5 V, making this device  
ideal for battery operated applications.  
select the amount of resolution appropriate for their applications  
without circuit card changes.  
The AD7396/AD7397 are specified for operation over the ex-  
tended industrial (–40°C to +85°C) temperature range. The  
AD7397AR is specified for the –40°C to +125°C automotive  
temperature range. AD7396/AD7397s are available in plastic  
DIP, and 24-lead SOIC packages. The AD7397ARU is avail-  
able for ultracompact applications in a thin 1.1 mm height  
TSSOP 24-lead package.  
A 12-bit wide data latch loads with a 45 ns write time allowing  
interface to fast processors without wait states. The double  
buffered input structure allows the user to load the input  
registers one at a time, then a single load strobe tied to both  
LDA+LDB inputs will simultaneously update both DAC out-  
puts. LDA and LDB can also be independently activated to  
immediately update their respective DAC registers. An address  
input (A/B) decodes DACA or DACB when the chip select CS  
input is strobed. Additionally, an asynchronous RS input sets  
the output to zero-scale at power on or upon user demand.  
Power shutdown to submicroamp levels is directly controlled by  
the active low SHDN pin. While in the power shutdown state  
register data can still be changed even though the output buffer  
is in an open circuit state. Upon return to the normal operating  
state the latest data loaded in the DAC register will establish the  
output voltage.
