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.
With an external op amp the AD5552 can be operated in bipo-
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.
The AD5551 and AD5552 are available in an SO package.

PRODUCT HIGHLIGHTS
1. Single Supply Operation.
The AD5551 and AD5552 are fully specified and guaranteed
for a single 5 V ± 10% supply.
2. Low Power Consumption.
Typically 1.5 mW with a 5 V supply.
3. 3-Wire Serial Interface.
4. Unbuffered output capable of driving 60 kΩ loads, which
reduces power consumption as there is no internal buffer
to drive.
5. Power-On Reset Circuitry.
