TDA7388A

Overview

The TDA7388A is a Class-AB audio power amplifier in Flexiwatt-EP-27 package. It delivers 42 W output into 4 Ohms, with THD+N at 0.04%. Operating voltage ranges from 8 V to 18 V. Gain is fixed at 26 dB, supporting 4 channels. Output current reaches 5.5 A. It operates between -40 C and +105 C, featuring AEC-Q100 qualification.

Feature Summary

Fully complementary PNP/NPN output configuration enabling rail-to-rail voltage swing without bootstrap capacitors
Integrated diagnostic capabilities including clipping detector, offset detector, and thermal shutdown monitoring
Comprehensive protection mechanisms against output short circuits, load dump voltage, and reversed battery conditions

Applications

High-end car radio applications
Automotive infotainment systems
Quad bridge speaker driving setups

Procurement Notes

Verify the specific suffix HLX for packaging details. Confirm AEC-Q100 automotive qualification status. Check Flexiwatt-EP-27 lead frame compatibility. Ensure supply voltage matches 8V-18V range. Validate thermal management requirements for high-power operation.

Selection Notes

Choose this component for compact designs requiring high output power with minimal external components. The fixed gain eliminates external compensation needs. Rail-to-rail output maximizes dynamic range. Integrated diagnostics simplify system monitoring and fault detection in automotive environments.

Part Context

Part of STMicroelectronics' automotive audio amplifier portfolio. Designed for high-reliability vehicle infotainment. Competes with other quad bridge amplifiers in the TDA73xx series. Focuses on efficiency and diagnostic integration for modern car radios.

Replacement Considerations

TDA7388: Similar quad bridge architecture but uses Flexiwatt-25 package and SMD mounting. Verify pinout compatibility and thermal performance differences before substitution.
