The RDA8506-X is powered by an external power supply with a voltage range of 2.7V to 5.5V.
The chip has multiple power domains, including the core power domain, analog power domain, and I\/O power domain, which need to be powered according to different functional modules.
At the same time, in order to ensure the stability and reliability of the chip, it is also necessary to carry out power filtering and voltage regulation.
Therefore, the power supply principle of the RDA8506-X is based on the external power supply to provide a stable voltage, and the corresponding power management and control through the internal power domain and power management module to ensure the normal operation and performance of the chip.
RDA8506-X chip is an audio decoding chip. Its power supply principle is that the normal working voltage is DC2.7V-5.5V. Its internal circuit adopts the structure of multiple power supplies, that is, different power combinations are used in different working modes. In addition, in most cases, the normal power supply voltage and interference can meet the working needs of the chip, and there will be no stability problems such as insufficient power supply.
