Application Scenarios & Design Considerations

3 BAND DIGITAL CONTROLLED AUDIO PROCESSOR

Alternative Part Number

  • PT2313L --: Audio tone/volume processor with I2C control, functionally similar to the TDA7319 and commonly used as a drop-in replacement in audio systems.
  • TDA7440 --: Audio processor with volume, tone and balance control in the same family of ST audio ICs, offering comparable functionality.
  • LM1036 --: Dual audio tone and volume control IC with similar analog control functions, suitable for audio preamp applications.
  • TDA7439 --: Same manufacturer family audio processor offering input selection, volume, bass and treble control, making it a close functional substitute.
  • LM1036N --: Dual-channel tone and volume control IC that can replace the TDA7319 in basic audio control applications with minor circuit adjustments.
