E-TDA7379

Audio Amplifiers Overview

The E-TDA7379 is a digitally controlled audio processor manufactured by STMicroelectronics, belonging to the TDA7379 series. It serves as an alternative to the standard TDA7379 AB-class audio power amplifier. The device supports 2-channel or 4-channel configurations with a supply voltage range of 8V to 20V. In a 4-ohm load configuration, it delivers up to 16W per channel in quad mode. It utilizes through-hole Multiwatt-15 packaging and meets AEC-Q100 automotive qualification standards.

Audio Amplifiers Feature Summary

• Digitally controlled audio processing capabilities integrated within the TDA7379 series architecture
• Supports flexible dual bridge or quad single-ended output configurations for stereo or four-channel setups
• Includes diagnostic facilities such as clip detection and fault monitoring for assembly verification
• Features CMOS-compatible standby functionality without audible pop during transitions

Audio Amplifiers Applications

• Automotive audio systems requiring digital control integration
• High-end car radio equipment designs
• Portable audio devices needing robust power amplification
• Home audio systems utilizing multi-channel configurations

Audio Amplifiers Procurement Notes

Verify component authenticity carefully as the standard TDA7379 is marked as obsolete. Confirm that the E-TDA7379 variant specifically provides the required digital control features rather than just passive amplification. Check for AEC-Q100 certification if automotive reliability is mandatory. Ensure the Multiwatt-15 through-hole package matches your PCB footprint requirements before finalizing orders.

Audio Amplifiers Selection Notes

Select this component when digital audio processing is needed alongside power amplification in the TDA7379 form factor. It is suitable for designs requiring 8V to 20V operation and high efficiency. Consider it for applications where the standard TDA7379 is unavailable but similar performance is required. Evaluate thermal management needs given the 36W dissipation rating at 85°C case temperature.

Audio Amplifiers Part Context

This part belongs to the TDA7379 family of Class-AB audio power amplifiers developed by STMicroelectronics. While the base TDA7379 is a legacy component now discontinued, the E-TDA7379 represents a specialized version with added digital control interfaces. It maintains the core fully complementary output stage structure designed for minimal external component count and high power performance in automotive and consumer audio environments.

Audio Amplifiers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify compatibility with existing circuit layouts when transitioning from the standard TDA7379 due to potential differences in digital control pinouts.
