The TDA7719TR 3 Band Car Audio Processor manufactured by STMicroelectronics is an integrated digital audio processor integrated circuit (IC) for car stereo line level control applications. The IC contains three independent stereo channels which can be used as separate amplifiers or mixed individually for a single 3 band output. The IC incorporates functions such as level control, 5 band equalizer, loudness, fade and balance, and MUTE capability. It also contains a mute control interface, pre-gain and post-gain controls, headphone output control, and mute/shutdown controls. The IC comes with a low standby current so it can be used with modern eco-friendly driving systems. The IC is designed to provide an optimal sound experience with minimal external components.
