TDA7388AEP-HLX

Overview

The TDA7388AEP-HLX is a Class-AB audio power amplifier manufactured by STMicroelectronics, designed for high-end car radio applications. It features four bridge-tied load channels delivering up to 42 W into a 4 Ohm load with a gain of 26 dB and THD+N of 0.04%. The device operates on an 8 V to 18 V supply range and supports output currents up to 5.5 A. It utilizes a Flexiwatt-EP-27 through-hole package and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Rail-to-rail output voltage swing enabled by fully complementary PNP/NPN output configuration without bootstrap capacitors
• Integrated diagnostic capabilities including clipping detector, offset detector, and thermal shutdown protection
• Low external component count due to internally fixed gain and absence of external compensation requirements

Applications

• High-end car radio systems
• Automotive audio power amplification
• Four-channel speaker driving in vehicle infotainment units

Procurement Notes

Verify the specific suffix HLX against the manufacturer's current datasheet to confirm exact packaging and reel specifications. Ensure the Flexiwatt-EP-27 through-hole package matches your PCB footprint requirements. Confirm AEC-Q100 compliance if automotive reliability certification is mandatory for your design. Check for any recent product change notices that may affect pinout or electrical characteristics.

Selection Notes

Select this component when designing automotive audio systems requiring high power output with minimal external circuitry. The integrated diagnostics and low distortion make it suitable for premium sound quality applications. Consider the thermal management requirements associated with the Flexiwatt-EP-27 package during high-power operation. Verify compatibility with 14.4 V automotive electrical systems.

Part Context

The TDA7388AEP-HLX belongs to the TDA7388 family of Class-AB audio amplifiers from STMicroelectronics. This series is specifically engineered for automotive environments, offering robust performance under varying voltage conditions. The EP variant typically denotes an exposed pad for enhanced thermal dissipation, distinguishing it from standard Flexiwatt packages.

Replacement Considerations

The TDA7388A is the base model within this family. Verify if the specific EP-27 package and HLX suffix are required for your assembly process, as other variants may use different packaging.
