TDA7467D$

Audio Special Purpose Overview

The TDA7467D is a stereo audio signal processor and matrix featuring licensed SRS (Sound Retrieval System) effects. It operates on a 7V to 10.2V supply within a -10°C to 85°C temperature range. The device supports two channels with I2C interface control for programmable functions including input attenuation, mono/stereo mode selection, and space/center attenuators. Packaged in a 28-SOIC surface-mount case, it integrates low distortion and low noise performance via BIPOLAR/CMOS/DMOS technology.

Audio Special Purpose Feature Summary

• Integrated SRS Audio Matrix for stereo and mono source processing
• Programmable via I2C serial bus for attenuation and mode control
• Low distortion and low noise using BIPOLAR/CMOS/DMOS technology
• Surface-mount 28-SOIC package

Audio Special Purpose Applications

• Signal mixing in consumer audio systems
• Audio matrix processing with spatial effects

Audio Special Purpose Procurement Notes

Verify the specific suffix 'D' against official STMicroelectronics documentation to confirm the 28-SOIC surface-mount variant. Confirm RoHS compliance status and current lifecycle status, as availability may vary. Ensure the I2C address configuration matches system requirements before procurement.

Audio Special Purpose Selection Notes

Select this component when an integrated solution for SRS-enhanced audio matrix processing is required. Verify that the 7V to 10.2V supply voltage aligns with the target system design. Consider the 28-SOIC package dimensions for PCB layout constraints compared to through-hole alternatives like the TDA7467.

Audio Special Purpose Part Context

This part belongs to the TDA7467 series of audio processors from STMicroelectronics. While the base TDA7467 is available in PDIP-28, the TDA7467D specifically denotes the surface-mount SOIC variant. It shares core functionality with other members of the family but differs in physical packaging and mounting style.

Audio Special Purpose Replacement Considerations

The TDA7467 serves as a direct functional equivalent in PDIP-28 packaging. For surface-mount replacements, verify pinout compatibility between the 28-SO and 28-SOIC packages if substituting with similar audio matrices.
