GENERAL DESCRIPTION  
The AD5551 and AD5552 are single, 14-bit, serial input, voltage  
output DACs that operate from a single 5 V 10% supply.

The AD5551 and AD5552 utilize a versatile 3-wire interface that  
is compatible with SPI, QSPI, MICROWIRE, and DSP inter-  
face standards.

These DACs provide 14-bit performance without any adjust-  
ments. The DAC output is unbuffered, which reduces power  
consumption and offset errors contributed by an output buffer.  
PRODUCT HIGHLIGHTS  
1. Single Supply Operation.  
With an external op amp the AD5552 can be operated in bipo-  
The AD5551 and AD5552 are fully specified and guaranteed  
for a single 5 V 10% supply.  
lar mode generating a  
VREF output swing. The AD5552 also  
includes Kelvin sense connections for the reference and analog  
ground pins to reduce layout sensitivity. For higher precision  
applications, please refer to 16-bit DACs AD5541, AD5542,  
and AD5544.  
2. Low Power Consumption.  
Typically 1.5 mW with a 5 V supply.  
3. 3-Wire Serial Interface.  
The AD5551 and AD5552 are available in an SO package.  
4. Unbuffered output capable of driving 60 kloads, which  
reduces power consumption as there is no internal buffer  
to drive.  
5. Power-On Reset Circuitry.
