... 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 ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD5551/AD5552 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... Unipolar Output Operation These DACs are capable of driving unbuffered loads of 60 kΩ. Unbuffered operation results in low-supply current, typically 300 µA, and a low-offset error. The AD5551 provides a unipolar output swing ranging from REF configured to output both unipolar and bipolar voltages. Fig- ure 3 shows a typical unipolar output voltage circuit ...

... Figure 7 shows an interface between the AD5551/AD5552 and any MICROWIRE-compatible device. Serial data is shifted out on the falling edge of the serial clock and into the AD5551/ AD5552 on the rising edge of the serial clock. No glue logic is required as the DAC clocks data into the input shift register on the rising edge ...

... DIN DIN Decoding Multiple AD5551/AD5552s The CS pin of the AD5551/AD5552 can be used to select one of a number of DACs. All devices receive the same serial clock and serial data, but only one device will receive the CS signal at any one time. The DAC addressed will be determined by the decoder ...
