BA1451F Am Radio / Fm If Stereo System Ic

The BA3822LS, BA3822FS, BA3823LS, and BA3824LS are monolithic, five-point stereo graphic equalizer integrated circuits (ICs). Each IC features two channels, with five center frequencies for each channel that can be independently set using external capacitors. These ICs support a wide operating power supply voltage range (VCC = 3.5V to 14V) and are available in compact 24-pin SZI, P, and SSOP packages, depending on the model. This versatility makes them an excellent choice for home stereo systems, radio cassette players, and car stereos. The primary distinction among the ICs lies in the amount of boost and cut control available, allowing selection based on specific application requirements. Manufactured by ROHM Co. Ltd.

The BA3822 series of graphic equalizer ICs are designed to enhance audio signal processing by providing adjustable frequency response across multiple channels. Each IC operates with two independent audio channels, allowing for stereo sound enhancement. The five center frequencies, typically set at key audio range points, can be tailored using external capacitors, offering flexibility in tuning the audio output to suit various listening environments.

The operating voltage range of 3.5V to 14V allows these ICs to be integrated into a wide variety of electronic systems, ensuring compatibility with both low-power and standard audio applications. The compact 24-pin packages facilitate easy integration into both printed circuit boards (PCBs) and other electronic assemblies, making them suitable for space-constrained designs often found in consumer audio equipment.

In terms of application, the BA3822 series is particularly beneficial for devices that require enhanced audio control, such as home stereo systems, where users may desire to adjust sound characteristics based on personal preference. The radio cassette players and car stereos also benefit from the ability to customize audio output, adapting to different acoustic environments and listener preferences.

The differentiation among the BA3822, BA3823, and BA3824 models primarily revolves around the specific parameters of boost and cut control, which can be selected based on the needs of the application. This allows designers to choose the appropriate IC variant that aligns with their audio enhancement requirements, ensuring optimal performance in their respective applications.The BA3822LS BA3822FS BA3823LS and BA3824LS are monolithic, five-point stereo graphic equalizer ICs.
