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.
