Si4730/31 AM/FM Radio Receivers

The Si4730/31 ICs are the industry's first fully integrated, 100% CMOS AM/FM radio receivers. The Silicon Labs Si4730/31 AM/FM radio ICs provide the space savings and low-power consumption necessary for portable devices while delivering the high performance and design simplicity desired for all AM/FM solutions. 

Our Si473x-D60 devices are the industry’s first integrated AM/FM tuners with an AUXIN ADC. The Si473x-D60 tuners offer unparalleled integration, audio quality, and performance for consumer audio applications requiring low power dissipation, minimal board area, and exceptional audio processing. 

Offering unmatched integration and PCB space savings, the Si4730/31 ICs require only two external components and less than 15 mm² of board area. The Si473x-D60 tuners offer a stereo analog input and internal ADCs multiplexed with the radio tuner front-end to support auxiliary analog system inputs without the need for additional external ADCs.
