... The AD5332/AD5333/AD5342/AD5343 have a parallel interface. CS selects the device and data is loaded into the input registers on the rising edge of WR. The GAIN pin on the AD5333 and AD5342 allows the output range to be set Input data to the DACs is double-buffered, allowing simultaneous update of multiple DACs in a system using the LDAC pin ...

... 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 AD5332/AD5333/AD5342/AD5343 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. θ ...

... X = don’t care. REV. 0 AD5332/AD5333/AD5342/AD5343 POWER-DOWN MODE The AD5332/AD5333/AD5342/AD5343 have low power con- sumption, dissipating typically 0.69 mW with supply and 1.5 mW with supply. Power consumption can be further reduced when the DACs are not in use by putting them into power-down mode, which is selected by taking pin PD low. ...

... LDAC is taken low. This means that the refer- ence buffers and the output amplifier gain of multiple DAC devices can be controlled using common GAIN and BUF lines. The AD5333 and AD5342 databuses must be at least 10, and 12 bits wide respectively, and are best suited to a 16-bit data- bus system. ...
