GENERAL DESCRIPTION

The AD5551/AD5552 are single, 14-bit, serial-input, voltageoutput 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 adjustments. The DAC output is unbuffered, which reduces power consumption and offset errors contributed by an output buffer.

FEATURES

Full 14-bit performance

3 V and 5 V single supply operation

Low 0.625 mW power dissipation

1 μs settling time

Unbuffered voltage output capable of driving 60 kΩ

loads directly

SPI/QSPI/MICROWIRE-compatible interface standards

Power-on reset clears DAC output to 0 V (unipolar mode)

5 kV HBM ESD classification

APPLICATIONS

Digital gain and offset adjustment

Automatic test equipment

Data acquisition systems

Industrial process control
