9 Power Supply Recommendations

The device requires a 3.3-V nominal supply for AVDD. The device also requires a 3.3-V supply for DRVDD. There are no specific sequence power-supply requirements during device power-up. AVDD, and DRVDD can power up in any order. It is recommended that the analog supply be low noise, such as would be the case if each analog supply was generated by its own linear regulator. The digital supply would be much more tolerant of supply noise and a DC-DC switching supply could be suitable for DRVDD.

At each power-supply pin, a 0.1-μF decoupling capacitor should be kept close to the device. A separate decoupling capacitor group consisting of a parallel combination of 10-μF, 1-μF, and 0.1-μF capacitors can be kept close to the supply source.
