9 Power Supply Recommendations

The DAC3174 uses as many as three different power-supply voltages. Some of the DAC power supplies are noise sensitive. Table 33 is a summary of the various power supplies of the DAC. See the evaluation module schematics for an example power-supply implementation. Take care to keep clean power supply routing away from noisy digital supplies. Avoid placing digital supplies and clean supplies on adjacent board layers and use a ground layer between noisy and clean supplies, if possible. All supplies pins must be decoupled as close to the pins as possible using small value capacitors, with larger bulk capacitors placed further away.

Table 33. DAC Power Supplies

POWER SUPPLY VOLTAGE NOISE SENSITIVE RECOMMENDATION
IOVDD 1.8 V to 3.3 V No Digital supply (keep separate from noise-sensitive supplies)
CLKVDD18 1.8 V Yes Provide clean voltage and avoid spurious noise
DIGVDD18 1.8 V No Digital supply (keep separate from noise-sensitive supplies)
VDDA18 1.8 V Yes Provide clean voltage and avoid spurious noise
VDDDA33 3.3 V Yes Provide clean voltage and avoid spurious noise
VFUSE 1.8 V No Digital supply, connect to DIGVDD18
