10 Power-Supply Recommendations

The DACx750 family can operate within the specified single-supply range of 10 V to 36 V applied to the AVDD

pin. The digital supply, DVDD, can operate within the specified supply range of 2.7 V to 5.5 V or be powered by

the internal 4.6-V LDO. Switching power supplies and DC/DC converters often have high frequency glitches or

spikes riding on the output voltage. In addition, digital components can create similar high frequency spikes. This

noise can be easily coupled into the DAC output voltage or current through various paths between the power

connections and analog output. TI recommends including bulk and local decoupling capacitors to further reduce

noise. The current consumption on the AVDD pin and current ranges for the current output are listed in Electrical

Characteristics. The power supply must meet the requirements listed in this table.
