9 Power Supply Recommendations

9.1 Power Supply Filtering

The power pins on the DS125DF1610 are all internally shorted together on the BGA substrate. This allows board designers to more easily distribute the bypass capacitors for power supply filtering.

Power supply filtering typically consists of a bulk 22 µF capacitor with an array of 0.1 µF capacitors all placed near the device. Additional bypass capacitors or capacitors of different values may be required depending on system conditions. An example array of power supply filtering capacitors is shown in Figure 6.
