TDA7467

Audio Special Purpose Overview

The TDA7467 is a stereo audio signal processor integrating SRS (Sound Retrieval System) effects, manufactured by STMicroelectronics. It functions as an audio matrix with programmable attenuation controls for space and center channels. The device supports stereo and mono modes via I2C serial bus interface. It operates within a supply voltage range of 7V to 10.2V and an ambient temperature range of -10°C to 85°C. Packaged in a 28-DIP through-hole case, it utilizes bipolar/CMOS/DMOS technology for low distortion and noise performance.

Audio Special Purpose Feature Summary

• Integrates licensed SRS Sound Retrieval System for stereo and mono source processing
• Programmable input attenuation control with 0.5dB step resolution
• Independent space and center channel attenuators
• Full function control via I2C serial bus interface

Audio Special Purpose Applications

• Signal mixing in audio systems
• Stereo audio matrix processing
• Mono mode audio enhancement

Audio Special Purpose Procurement Notes

The TDA7467 is listed as a discontinued product with unavailable stock status. Verification of current availability requires checking authorized distributors or secondary market sources, as original manufacturing supply has ceased. Ensure compatibility with existing I2C bus architectures when considering legacy replacements.

Audio Special Purpose Selection Notes

Select this component for applications requiring integrated SRS spatial audio effects without external DSPs. Verify that the system design accommodates the 28-DIP through-hole package constraints. Confirm that the I2C bus speed and addressing align with the controller requirements. The operating temperature range suits standard commercial environments.

Audio Special Purpose Part Context

This part belongs to the TDA7467 series of analog audio processors from STMicroelectronics. It is categorized under Audio Special Purpose ICs. The device is distinct from power amplifiers like the TDA7318 or TDA7567PD, focusing solely on signal processing and matrixing rather than output driving.

Audio Special Purpose Replacement Considerations

As the TDA7467 is discontinued, no direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate newer ST audio processors with similar I2C control and SRS licensing capabilities, ensuring pinout and functional compatibility.
