The RDA5802E (RDA5802 Enhanced) is a single-chip broadcast FM stereo radio tuner with fully integrated synthesizer, IF selectivity and MPX decoder. The tuner 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 RDA5802E has a powerful low-IF digital audio processor, this make it have optimum sound quality with varying reception conditions.
The RDA5802E can be tuned to the worldwide frequency band.
