10 Power Supply Recommendations

The DACx0004 can operate within the specified supply voltage range of 2.7 V to 5.5 V. The power applied to VDD should be well-regulated and have low-noise. 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 easily couple into the DAC output voltage through various paths between the power connections and analog output. A 1 µF to 10 µF capacitor and 0.1 µF bypass capacitor is recommended in order to further minimize noise from the power supply. The current consumption on the VDD pin, the short-circuit current limit, and the load current for the device are listed in the Electrical Characteristics. The power supply must meet the aforementioned current requirements.
