Description
The Si4831/35-B30 is the 2nd generation mechanical-tuned digital CMOS AM/FM/SW radio receiver IC that integrates the complete receiver function from antenna input to audio output. Like other successful audio products from Silicon Labs, Si4831/35-B30 offers unmatched integration and PCB space savings with minimum external components and a small board area. The Si4831/35-B30 requires a simple application circuit and removes any requirements for manually tuning components during the manufacturing process. The Si4831/35-B30 is a very simple product to design, manufacture, and support across multiple product lines. The receiver has very low power consumption, runs off two AAA batteries, and delivers the performance benefits of digital tuning to the analog radio market.
