Application Scenarios & Design Considerations

DIGITAL CONTROLLED STEREO AUDIO PROCESSORWITH LOUDNESS

Alternative Part Number

  • PT2313L --: Pin-compatible audio processor with similar tone/volume/balance control functions, widely used as a direct substitute for TDA7313 in many designs.
  • TDA7439 --: Same ST audio processor family with I2C control and comparable input/output switching and tone control features, suitable functional replacement.
  • PT2314 --: Similar multi-input audio processor with volume, tone and balance control, often used as an alternative when TDA7313 is unavailable.
