Procurement Notes

The TDA7718N is listed as discontinued or obsolete by the manufacturer. Availability is restricted, and it may not be sold in all regions. Verify current stock status with authorized distributors before design finalization. Consider alternative components if long-term supply stability is required for production.

Selection Notes

Select this component for automotive designs requiring a dedicated 3-channel audio processor with I2C control. Ensure the system power supply remains within the 7.5V to 10V range. Confirm compatibility with the 28-TSSOP footprint during PCB layout. Verify that the application environment stays within the specified -40°C to +85°C operating temperature limits.

Part Context

This part belongs to STMicroelectronics' portfolio of audio ICs specialized for automotive use. It serves as a digital processor within the vehicle's audio chain, distinct from power amplifiers. The TDA7718 series includes variants like the TDA7718B, sharing similar core functionalities but potentially differing in specific electrical parameters or packaging details.

Replacement Considerations

As the TDA7718N is discontinued, direct replacements must be sourced from updated product lines. Check for newer STMicroelectronics automotive audio processors with compatible pinouts and I2C interfaces. Evaluate functional equivalence regarding channel count and processing features before substitution.
