E-TDA7396

Audio Amplifiers Overview

The E-TDA7396 is a single-channel bridge Class AB audio power amplifier from STMicroelectronics, designed for automotive high-power applications. It operates on an 8 V to 18 V supply and delivers 27 W output. The device features a 75 kHz gain-bandwidth product and utilizes a 11-pin Multiwatt package with through-hole mounting. It supports differential or single-ended inputs and includes integrated diagnostics.

Audio Amplifiers Feature Summary

• Supports both differential and single-ended input signal modes
• Includes onboard clipping detector for gain compression implementation
• Features automatic mute during turn-on/off to prevent audible pops
• Provides diagnostic facilities for assembly and wiring error detection

Audio Amplifiers Applications

• Car radio booster systems
• High-end car radio applications
• Automotive audio amplification

Audio Amplifiers Procurement Notes

Verify the specific suffix 'E' against the official datasheet to confirm if it denotes a specific tape-and-reel variant or packaging difference compared to the standard TDA7396. Ensure the Multiwatt-11 package dimensions match the design constraints. Confirm AEC-Q100 qualification status for the specific orderable part number before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when a single-channel bridge-tied load (BTL) configuration is required for automotive audio boosters. The internal fixed gain of 26 dB reduces external component count by eliminating bootstrap capacitors and Boucherot cells. The CMOS-compatible standby function allows easy integration into vehicle control logic.

Audio Amplifiers Part Context

This part belongs to the TDA7396 series of automotive audio amplifiers. It is distinguished by its single-channel BTL architecture and fully complementary output stage. Unlike stereo variants such as the TDA7393, this model focuses on high-power mono output capabilities suitable for subwoofer or main speaker driving in vehicle infotainment systems.

Audio Amplifiers Replacement Considerations

Direct substitutes within the same family include the standard TDA7396. Verify pinout compatibility and thermal performance characteristics when replacing with other STMicroelectronics automotive audio amplifiers.
