The R2A15908SP is an optimum audio signal processor IC for TV. It has a 5ch input selector with mono switch, surround, tone control (2band), input gain control and 2ch master volume. It can control all of these functions with I2C bus.

1. Audio Amplifiers: Audio amplifiers are used to boost the audio signal’s power to drive the TV’s built-in speakers or external speakers. These can be integrated into the TV’s circuitry.

2. Audio Codecs: Audio codecs are ICs that encode and decode audio signals. They are used for various audio formats, such as Dolby, DTS, and AAC. These codecs ensure compatibility with different audio sources and formats.

3. Digital Signal Processors (DSPs): DSP ICs are versatile and are used for a wide range of audio processing tasks, including equalization, surround sound processing, noise reduction, and echo cancellation. They can enhance the overall audio experience.



1. Volume 0 to –87dB, –∞ / 1dB step, Each channel is independent control.
