PRODUCT HIGHLIGHTS  
GENERAL DESCRIPTION  
1. Low power, single supply operation. This part operates from  
a single +2.7 V to +5.5 V supply and consumes typically  
15 mW at 5.5 V, making it ideal for battery powered  
applications.  
The AD7303 is a dual, 8-bit voltage out DAC that operates  
from a single +2.7 V to +5.5 V supply. Its on-chip precision out-  
put buffers allow the DAC outputs to swing rail to rail. This de-  
vice uses a versatile 3-wire serial interface that operates at clock  
rates up to 30 MHz, and is compatible with QSPI, SPI, microwire  
and digital signal processor interface standards. The serial input  
register is sixteen bits wide; 8 bits act as data bits for the DACs,  
and the remaining eight bits make up a control register.  
2. The on-chip output buffer amplifiers allow the outputs of the  
DACs to swing rail to rail with a settling time of typically 1.2 µs.  
3. Internal or external reference capability.  
4. High speed serial interface with clock rates up to 30 MHz.  
The on-chip control register is used to address the relevant  
DAC, to power down the complete device or an individual  
DAC, to select internal or external reference and to provide a  
synchronous loading facility for simultaneous update of the  
DAC outputs with a software LDAC function.  
5. Individual power-down of each DAC provided. When com-  
pletely powered down, the DAC consumes typically 80 nA.  
The low power consumption of this part makes it ideally suited  
to portable battery operated equipment. The power consump-  
tion is 7.5 mW max at 3 V, reducing to less than 3 µW in full  
power-down mode.  
The AD7303 is available in an 8-pin plastic dual in-line pack-  
age, 8-lead SOIC and microSOIC packages.

Microwire is a trademark of National Semiconductor.
