ADVANCE INFORMATION
Refer to the PDF data sheet for device specific package drawings
The DAC80516 operate within the specified AVDD supply range of 2.7V to 5.5V and VIO supply range of 1.7V to 5.5V. The DAC80516 does not require specific supply sequencing; however the serial interface requires 10ms to initalize and enable communication with the device.
The AVDD supply must be well-regulated and 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. To minimize noise from the power supply, include a 1μF to 10μF capacitor and 0.1μF bypass capacitor. The power supply must meet the input current requirements listed in Section 5.
