The RDA5830/1 is a single-chip broadcast FM/AM/LW/SW (LW/SW only for RDA5830) receiver with fully integrated synthesizer, IF selectivity and MPX decoder. The chip uses the CMOS process, support multi-interface and require the least external component. The package size is 4X4mm and is completely adjustment-free. All these make it very suitable for portable devices.
The RDA5830/1 has a powerful low-IF digital audio processor, this make it have optimum sound quality with varying reception conditions.
The RDA5830/1 use auto frequency calibration, this make it have perfectly performance and agility.
The RDA5830/1 support world band FM/AM （RDA5831 alos suppory LW/SW） frequency band receive, support weather band and also support RDS/RBDS receive .
The RDA5830/1 directly support wide power supply range (1.8V~5V).
