TDA7303TR

Audio Special Purpose Overview

The TDA7303TR is a two-channel audio tone processor manufactured by STMicroelectronics, designed for automotive applications. It operates on a supply voltage of 6V to 10V and features an I2C interface for control. The device is housed in a 28-SOIC package with a width of 7.50mm. It meets AEC-Q100 qualification standards and functions within a temperature range of -40°C to 85°C. The component specifies a performance parameter of 1.25dB.

Audio Special Purpose Feature Summary

• Two-channel audio tone processing capability
• I2C digital interface for configuration
• AEC-Q100 qualified for automotive grade reliability
• Operates within 6V to 10V supply voltage

Audio Special Purpose Applications

• Automotive audio systems
• Car radio tone control
• Vehicle infotainment signal processing

Audio Special Purpose Procurement Notes

The TDA7303TR is currently listed as obsolete or discontinued by the manufacturer. Verification of availability should focus on remaining stock from authorized distributors or secondary market sources. Buyers must confirm the specific revision level and packaging type (Tape & Reel) against current inventory records before procurement planning.

Audio Special Purpose Selection Notes

Select this component only if legacy automotive audio designs require a dedicated two-channel tone processor with I2C control. Ensure the system design accommodates the 6V to 10V supply range and the 28-SOIC footprint. Verify that the 1.25dB specification aligns with the required audio signal integrity for the target application.

Audio Special Purpose Part Context

This part belongs to the TDA7303 series of audio integrated circuits. The 'TR' suffix indicates the component is supplied in a Tape & Reel format, suitable for automated surface mount assembly processes. It is distinct from other ST audio amplifiers which may offer power output stages rather than signal processing.

Audio Special Purpose Replacement Considerations

As the product is obsolete, direct replacements are not officially confirmed in public documentation. Engineers should evaluate newer ST automotive audio processors with similar I2C interfaces and channel counts, ensuring pin compatibility and functional equivalence for the tone processing requirements.
