E-TDA7384A

Audio Amplifiers Overview

The E-TDA7384A is a Class-AB audio power amplifier designed for high-end car radio applications. It features four channels with a maximum output power of 45 W per channel at 4 Ω. The device operates within an 8 V to 18 V supply voltage range and utilizes a fully complementary PNP/NPN configuration for rail-to-rail output swing without bootstrap capacitors. Key electrical parameters include a fixed internal gain of 26 dB, a 25-pin Flexiwatt package, and through-hole mounting.

Audio Amplifiers Feature Summary

• Supports standby and mute functions for power management
• Includes automute capability triggered by minimum supply voltage detection
• Features comprehensive protection against output short circuits, overtemperature, load dump, reversed battery, and fortuitous open ground conditions

Audio Amplifiers Applications

• High-end automotive radio systems
• Car audio amplification circuits

Audio Amplifiers Procurement Notes

Verify the specific suffix 'E' in the part number E-TDA7384A against official STMicroelectronics documentation to confirm exact manufacturing specifications or environmental compliance status. Ensure compatibility with the required 25-Flexiwatt vertical package form factor for your PCB layout. Confirm that the through-hole installation method aligns with your assembly process requirements before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when designing automotive audio systems requiring a quad-channel Class-AB amplifier with robust protection features. It is suitable for applications needing rail-to-rail output swing without external bootstrap components. Consider its 25-pin Flexiwatt package and through-hole mounting style for thermal management and mechanical integration in vehicle infotainment units.

Audio Amplifiers Part Context

The TDA7384A belongs to STMicroelectronics' portfolio of Class-AB audio power amplifiers tailored for automotive use. This series emphasizes high output power and low distortion while minimizing external component count. The E-TDA7384A variant maintains the core functionality of the TDA7384A family, offering four-channel amplification with integrated protections for reliable operation in harsh automotive environments.

Audio Amplifiers Replacement Considerations

The TDA7384B is documented as a related model within the same product family, sharing identical pinout and functional characteristics but differing in package orientation (horizontal vs. vertical). Verify if the TDA7384A serves as a direct substitute, noting potential differences in packaging or specific revision details.
