Application Scenarios & Design Considerations

ADVANCED CAR SIGNAL PROCESSOR

Alternative Part Number

  • TDA7400 --: Same TDA7400 audio processor die in a different package/ordering variant, so the core function and register set match closely; verify package and pinout before use.
  • TDA7401 --: Closely related ST audio processor in the same TDA74xx family with similar signal-processing features; check pin compatibility and control interface.
  • TDA7439 --: ST sound processor with comparable audio control functions (volume, tone, input selection); requires verification of I2C addressing and pinout differences.
  • TDA7419 --: ST audio processor with comparable car-radio sound processing functions; requires design verification of control interface and pinout.
