Application Scenarios & Design Considerations

I2C-bus controlled BTSC stereo/SAP decoder and audio processor

Alternative Part Number

  • TDA8425 --: Same TDA-series audio processor family from the original manufacturer's successor, offering comparable stereo audio processing functions and similar supply requirements.
  • TDA7439 --: Audio processor IC with I2C-controlled tone, volume and balance functions, functionally similar to the TDA9855 and widely available as a replacement in audio systems.
  • LM1036 --: Analog tone and volume control IC providing comparable audio processing capability, usable as a functional substitute where the TDA9855 is unavailable.
  • TDA7440 --: Similar I2C audio processor for TV and audio applications, offering volume, balance, tone and input switching functions as a functional replacement.
