Overview
The TDA7387EPAG 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. Key electrical characteristics include an internally fixed gain of 26 dB and operation within a supply voltage range of 18 V to 28 V DC.
Feature Summary
- High output power capability with low distortion and noise
- Rail-to-rail output swing eliminating the need for bootstrap capacitors
- Integrated protections including short circuit, overtemperature, and load dump
- Compact design enabled by extremely reduced boundary component count
Applications
- High-end car radio systems
- Automotive audio amplification
- Quad bridge speaker driving in vehicles
Procurement Notes
Verify the specific suffix EPAG against the manufacturer's official datasheet to confirm package type and compliance status. Ensure the ordering part number matches the exact Flexiwatt-25 variant required for your thermal and mechanical design constraints before finalizing procurement.
Selection Notes
Select this component when designing automotive audio systems requiring high power output from a Class-AB topology. The absence of bootstrap capacitors simplifies the bill of materials and reduces board space requirements. Verify that the application supports the 18 V to 28 V DC operating voltage range typical for automotive environments.
Part Context
This part belongs to STMicroelectronics' family of Class-AB automotive audio power amplifiers. It is specifically engineered for vehicle infotainment systems where high fidelity and robust protection features are critical. The Flexiwatt-25 package provides efficient heat dissipation for sustained high-power operation in confined automotive spaces.
Replacement Considerations
Consult official substitution guides for compatible alternatives such as the TDA7388 or TDA7388A. Verify pin compatibility and thermal performance before swapping components to ensure system integrity.
