5.1 Power Pins
It is recommended that a bulk and a decoupling capacitor be added at the input supply pin (VDD, VDD_A and GND pins) of the RNBD451 module.
- It is recommended to add a 4.7 μF and a 0.1 μF cap on both VDD and VDD_A pins.
- The value of the capacitors are based on typical application requirements and are the minimum recommended values. Depending on the application requirement (in other words, a noisy power line or other known noise sources), the values of capacitors can be adjusted to provide a clean supply to the module.
- All capacitors must be placed close to the Module Power supply pins.
