It functions within an ambient temperature range of -40°C to 85°C and meets automotive grade standards.

Feature Summary

• Six-channel audio signal processing capability
• I2C digital interface for control
• Automotive grade qualification
• Wide operating voltage range (4.5V to 13V)

Applications

• Automotive audio systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Ensure compatibility with system voltage requirements and I2C bus configurations before integration. Confirm that the automotive grade rating aligns with target application environmental constraints.

Selection Notes

Select this component for designs requiring multi-channel audio processing in vehicles. Verify that the 28-TSSOP footprint fits the PCB layout. Ensure the controller supports the required I2C protocol for configuration. Check thermal management needs for the specified operating temperature range.

Part Context

This part belongs to the TDA7729 series of audio processors. The TR suffix indicates Tape and Reel packaging. It is distinct from power amplifiers like the TDA7294, focusing instead on signal processing rather than high-power output stages.
