描述 Description

Si4731 ICs are?the industry's first fully integrated, 100% CMOS AM/FM radio receivers, providing 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 Si4731devices 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?Si4731 ICs require only two external components and less than 15 mm2?of board area. 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.?
