SKYWORKS SI4820-A10-CUR

The Si4820/24-A10 is the entry level mechanical-tuned digital CMOS AM/FM/SW radio receiver IC that integrates the complete receiver function from antenna input to audio output. The Si4820/24-A10 extends Skyworks multi-band tuner family, and further increases the ease and attractiveness of design radio reception to audio devices through small size and board area, minimum component count, and superior, proven performance. The Si4820/24-A10 is drop-in replaceable to the existing Si4831/35 tuner, requires a simple application circuit, and removes any requirements for manually tuning components during the manufacturing process. It 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.
