The Si4825 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 Si4825 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 Si4825 requires a simple application circuit
and removes any requirements for manually tuning components during the
manufacturing process. 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.
