Procurement Notes

Verify the specific revision level and manufacturing date code against current STMicroelectronics documentation before procurement. Confirm that the 28-TSSOP tape and reel packaging aligns with automated assembly requirements. Ensure compatibility with the target vehicle's electrical system voltage ranges.

Selection Notes

Select this component when a multi-channel audio processor with I2C control is required for automotive environments. Compare specifications such as the 100dB metric against alternative processors like the TDA7719 or TDA7729 if channel count or interface differences are critical to the design.

Part Context

This part belongs to the family of STMicroelectronics automotive audio signal processors. It complements other models such as the TDA7719 and TDA7729, which offer similar functionalities but may differ in channel configuration or specific feature sets. These components are commonly integrated into modern vehicle sound systems.

Replacement Considerations

Check for direct pin-to-pin replacements within the same product family. Verify functional equivalence regarding channel count and interface protocols before substituting with other audio processors.
