S6522BT9 is an integrated circuit by Sanyo Semiconductor. It is a surface-mount, single-chip dual band FM/AM radio receiver IC for portable audio products. It is ideal for applications that require a high level of integration and support for both FM and AM bands. The S6522BT9 IC combines the function of a radio receiver, IF amplifier, matching networks, and antenna matching networks into one package.

The S6522BT9 works by capturing and amplifying radio signals in the AM and FM frequency bands. The radio signal is filtered and amplified by the on-chip IF amplifier before being passed to the demodulator. The demodulator transforms the radio signal into base band audio signals. The audio signals are then sent to the audio amplifier stage and then to the speaker or headphone.

The S6522BT9 can be used in a wide variety of applications, including car radios, mobile phones, MP3 players, personal digital assistants, and portable radios. Battery operated devices, such as portable radios and MP3 players, can benefit from the S6522BT9’s low power consumption. It is also used in some CB radios and walkie-talkies to support short-range communications.

The S6522BT9 also supports AM and FM stereo reception and provides built-in advanced features such as Automatic Gain Control, AM/FM selectivity, and noise cancelling. It supports low impedance loads, enabling it to be connected directly to speakers without an intermediate amplifier. The S6522BT9 also has an on-chip temperature compensator to ensure optimum performance in all environmental conditions.

Due to its low power consumption, high performance, and ability to support both AM and FM reception, the S6522BT9 is an ideal choice for portable radio applications. It is a reliable and cost effective solution for a wide range of consumer and industrial applications.
