TDA7379 General Description

The TDA7379 is a dual bridge audio power amplifier IC that can drive two sets of stereo speakers or a single set of speakers with higher power output. It's commonly used in car audio systems and other audio applications.

The TDA7379 is an integrated circuit (IC) designed for audio amplification applications. It is a quad audio amplifier IC, meaning it can amplify audio signals for four separate channels, typically used for stereo left and right channels for both front and rear speakers. 



Quad Audio Amplifier: The TDA7379 is designed to amplify audio signals for four channels, making it suitable for stereo audio systems with front and rear speakers.

Output Power: The IC is capable of delivering significant output power, allowing it to drive speakers with sufficient volume. The exact power output depends on operating conditions and supply voltage but is typically in the range of several watts per channel.

Operating Voltage: The TDA7379 operates from a supply voltage in the range of approximately 8V to 18V, making it suitable for automotive and low-voltage applications.

Low Distortion: It is designed to provide low distortion and high-quality audio amplification, ensuring clear and crisp sound reproduction.

Thermal Protection: The IC typically includes thermal protection features to prevent overheating, which is crucial for maintaining the reliability of the amplifier.

Short-Circuit Protection: Many versions of the TDA7379 include short-circuit protection to safeguard the amplifier and connected speakers from damage in case of a short circuit.

Package Options: The IC is available in various package options, including the Multiwatt15 and Flexiwatt25 packages, providing flexibility for different circuit board designs.



Car Audio Systems: It is commonly used in car stereo amplifiers to drive speakers in the vehicle, providing audio playback for passengers. The quad-channel design is suitable for front and rear speakers.

Home Audio Systems: The IC can be used in home theater systems and audio receivers to amplify audio signals for speakers in multiple rooms or zones.

Portable Audio Devices: In some cases, it can be used in portable audio devices such as portable speakers and boomboxes.

Other Audio Amplification: The TDA7379 can be used in various applications where audio amplification is needed, such as public address systems, multimedia speakers, and amplifiers for musical instruments.
