GENERAL DESCRIPTION
The AD5551/AD5552 are single, 14-bit, serial-input, voltage-
output DACs that operate from a single 2.7 V to 5.5 V supply.
The DAC output range extends from 0 V to VREF.
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
bipolar 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
and AD5544.
The AD5551/AD5552 utilize a versatile 3-wire interface that is
compatible with SPI, QSPI, MICROWIRE, and DSP interface
standards. The AD5551 and AD5552 are available in 8-lead and
14-lead SOIC packages.

PRODUCT HIGHLIGHTS
1.
Single Supply Operation.
The AD5551 and AD5552 are fully specified and
guaranteed for a single 2.7 V to 5.5 V supply.
2.
Low Power Consumption.
Typically 0.625 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.
