9 Power Supply Recommendations

All supplies may be generated from a common nominal 5 V source but should be isolated through decoupling

capacitors placed close to the device. The typical application schematic in Figure 13 is an excellent example.

Select capacitors with self-resonant frequency near the application frequency. When multiple capacitors are used

in parallel to create a broadband decoupling network, place the capacitor with the higher self-resonant frequency

closer to the device. Expensive tantalum capacitors are not needed for optimal performance.
