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. 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 precision applications， refer to 16-bit DACs AD5541， AD5542， 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.
