TDA7468D

TDA7468D Description

The TDA7468D from STMicroelectronics is a high-performance 2-channel audio tone processor designed for consumer audio applications. Operating within a 5V to 10V supply range, this IC integrates advanced Automatic Level Control (ALC) and surround sound processing, making it ideal for enhancing audio quality in compact systems. Its I2C interface enables precise digital control over tone adjustments, while its surface-mount 28SO package ensures compatibility with modern PCB designs. Although marked as obsolete, the TDA7468D remains a reliable choice for legacy designs requiring robust audio processing with minimal external components.

TDA7468D Features

• 2-channel audio processing with ALC and surround sound capabilities for immersive listening experiences.
• Wide voltage supply range (5V–10V), accommodating diverse system power requirements.
• I2C digital control interface for flexible and precise adjustment of tone, balance, and volume settings.
• Surface-mount 28SO package, optimized for space-constrained applications.
• ROHS3 compliant and REACH unaffected, meeting environmental and safety standards.
• Moisture Sensitivity Level (MSL 3) ensures reliability in humid environments (168-hour floor life).

TDA7468D Applications

The TDA7468D excels in consumer audio systems such as:

• Home theater receivers, where its surround sound processing enhances spatial audio effects.
• Compact stereo systems, leveraging its ALC to maintain consistent output levels across varying input signals.
• Television audio modules, benefiting from its I2C-controlled tone adjustments for optimized sound profiles.
• Legacy audio equipment repairs, where its discontinued status may still align with existing designs.

Conclusion of TDA7468D

While the TDA7468D is obsolete, its combination of ALC, surround processing, and I2C control makes it a historically significant IC for audio systems. Engineers seeking a proven, integrated solution for tone management and audio enhancement in constrained designs may still find value in remaining stock or compatible alternatives. Its low external component count and robust performance underscore STMicroelectronics' legacy in audio IC innovation.
