GENERAL DESCRIPTION  
A double buffered serial data interface offers high speed, three-  
wire, DSP and SPI microcontroller compatible inputs using  
data in (SDI), clock (CLK) and load strobe (LDA + LDB)  
pins. A chip-select (CS) pin simplifies connection of multiple  
DAC packages by enabling the clock input when active low.  
Additionally, an RS input sets the output to zero scale or to 1/2  
scale based on the level applied to the MSB pin. A power  
shutdown feature reduces power dissipation to less than 3 µW.  
The AD8303 is a complete (includes internal reference) dual,  
12-bit, voltage output digital-to-analog converter designed to  
operate from a single +3 volt supply. Built using a CBCMOS  
process, this monolithic DAC offers the user low cost and ease-  
of-use in single-supply +3 volt 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.  
The 2.0475 V full-scale voltage output is laser-trimmed to  
maintain accuracy over the operating temperature range of the  
device. The binary input data format provides an easy-to-use  
one-half millivolt-per-bit software programmability. The voltage  
outputs are capable of sourcing 3 mA.  
The AD8303 is specified over the extended industrial (–40°C to  
+85°C) temperature range. AD8303s are available in plastic  
DIP and low profile 1.75 mm height SO-14 surface mount  
packages. For single-channel DAC applications, see the  
AD8300 which is offered in the 8-lead DIP and SO-8 packages.
