GENERAL DESCRIPTION  
in (SDI), clock (CLK) and load strobe (LD) pins. Addition-  
ally, a CLR input sets the output to zero scale at power on or  
upon user demand.  
The AD7390/AD7391 family of 10-bit and 12-bit voltage-  
output digital-to-analog converters is 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 consuming less than 100 µA  
making this device ideal for battery operated applications.  
Both parts are offered in the same pinout to allow users to select  
the amount of resolution appropriate for their application without  
circuit card redesign.  
The AD7390/AD7391 are specified over the extended industrial  
(ꢀ40°C to ꢁ85°C) temperature range. The AD7391AR is  
specified for the ꢀ40°C to ꢁ125°C automotive temperature  
range. The AD7390/AD7391s are available in plastic DIP, and  
low profile 1.75 mm height SO-8 surface mount packages. The  
AD7391ARU is available for ultracompact applications in a thin  
1.1 mm TSSOP-8 package.  
The full-scale voltage output is determined by the external  
reference input voltage applied. The rail-to-rail REFIN to  
DACOUT allows for a full-scale voltage set equal to the positive  
supply VDD or any value in between.  
A doubled-buffered serial-data interface offers high-speed,  
3-wire, SPI and microcontroller compatible inputs using data
