Audio Special Purpose Procurement Notes

The TDA7318D is listed as a discontinued product with an expiration date of July 3, 2026. Verification of current availability status and end-of-life timelines should be confirmed directly with the manufacturer or authorized distributors before procurement planning.

Audio Special Purpose Selection Notes

Select this component for automotive audio designs requiring integrated tone control via I2C. Ensure the system design accommodates the 6V to 10V supply range and the thermal requirements of the 28-SOIC package within the specified -40°C to 85°C operating environment.

Audio Special Purpose Part Context

This part belongs to the TDA7318 family of audio processors. It is distinct from power amplifiers like the TDA7567PD or HFDA80D series, focusing specifically on tone processing rather than high-power output stages.

Audio Special Purpose Replacement Considerations

As the product is discontinued, verify if newer STMicroelectronics automotive audio tone processors are available as direct replacements. Check pin compatibility and software register maps for any necessary design adjustments.
