Application Scenarios & Design Considerations

DIGITALLY CONTROLLED AUDIO PROCESSOR WITH LOUDSPEAKERS EQUALIZER

Alternative Part Number

  • TDA7400 --: Same TDA740x audio processor family from ST with nearly identical function and pinout, making it a direct drop-in substitute in most applications.
  • TDA7419 --: ST audio processor with comparable signal processing features and supply requirements, suitable as a functional replacement with minor circuit adaptation.
  • BD37534FV --: Rohm sound processor offering similar audio control functions and voltage range, usable as a cross-manufacturer alternative when ST parts are unavailable.
