Overview
The TDA7387EP is a Class AB audio power amplifier designed for high-end car radio applications. It features a fully complementary PNP/NPN configuration enabling rail-to-rail output voltage swing without bootstrap capacitors. The device delivers 4 x 41 W into 4 Ω loads with low distortion and noise. Key internal features include fixed gain (26 dB), automute at minimum supply voltage, and comprehensive protections against short circuits, overtemperature, load dump, reversed battery, and fortuitous open ground.
Feature Summary
- Rail-to-rail output capability using fully complementary PNP/NPN configuration
- Integrated automute function triggered by minimum supply voltage detection
- Comprehensive protection suite including thermal limiting and reverse battery handling
Applications
- High-end automotive radio systems
- Car audio amplification modules
Procurement Notes
Verify the Flexiwatt-25 package orientation and pinout compatibility during integration. Confirm that the specific suffix 'EP' denotes lead-free compliance as per manufacturer standards. Ensure design accounts for the fixed internal gain of 26 dB to prevent signal clipping. Validate thermal management requirements given the discrete component count and power dissipation characteristics in enclosed vehicle environments.
Selection Notes
Select this component for designs requiring high output power with minimal external compensation components. The absence of bootstrap capacitors simplifies the bill of materials and reduces board space. Ideal for applications prioritizing robust protection features like automute and load dump immunity over digital control interfaces.
Part Context
This part belongs to STMicroelectronics' portfolio of Class AB automotive audio amplifiers. It is distinct from Class D alternatives like the HFDAX0D series, offering analog performance with simpler control requirements. The TDA7387EP serves as a specialized solution for traditional car radio architectures rather than modern digital infotainment systems.
Replacement Considerations
The TDA7387 is the base model variant. Verify if the 'EP' suffix strictly indicates environmental compliance or if functional differences exist in the specific datasheet revision.
