9.4 Power Supply Recommendations

Although the OPT4048 has low sensitivity to power-supply noise, good practices are always recommended. For best performance, the OPT4048 VDD pin must have a stable, low-noise power supply with a 100-nF bypass capacitor close to the device and solid grounding. There are many options for powering the OPT4048 because of the device low current consumption levels.
