Audio Special Purpose Procurement Notes

The TDA7419TR is listed as a discontinued product by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of end-of-life status and potential obsolescence is required before procurement planning. Alternative components should be evaluated for long-term design sustainability.

Audio Special Purpose Selection Notes

Select the TDA7419TR for automotive audio designs requiring integrated DSP functions with I2C digital control. Ensure the power supply maintains 8V to 10V stability. The 28-SOIC package requires surface mount assembly. Verify compatibility with existing filter characteristics programming requirements and confirm that the AEC-Q100 grade meets specific automotive reliability standards.

Audio Special Purpose Part Context

The TDA7419TR belongs to the TDA7419 series of audio processors from STMicroelectronics. It utilizes BICMOS process technology to achieve low distortion and low noise performance. The device integrates linear signal processing and programmable audio filters, distinguishing it from standard amplifiers by focusing on signal conditioning and routing rather than power output.

Audio Special Purpose Replacement Considerations

As the TDA7419TR is discontinued, no direct public substitute part numbers are confirmed in the provided documentation. Designers must evaluate alternative automotive audio DSPs with compatible pinouts and I2C interfaces.
