Si4825/31/35/36 Mechanically-Tuned AM/FM Radio Receivers

Si4825/31/35/36 devices are mechanically-tuned digital display CMOS AM/FM/SW radio receiver ICs that integrate the complete receiver function from antenna input to audio output. Si482x/3x devices offer unmatched integration and PCB space savings with minimum external components and a small board area. Si482x/3x ICs require a simple application circuit and remove requirements for manually tuning components during the manufacturing process.

Si4820/24/25 devices are drop-in compatible with Si4831/35/36 devices, making them a simple product to design, manufacture, and support across multiple product lines. Powered by two AAA batteries, the receiver has ultra-low power consumption and delivers the performance benefits of digital tuning to the AM/FM/SW analog radio market. For consumer applications that require EN55020 compliance, use Si4831/35/36 devices.
