- Short-circuit protection  
- Thermal protection  
- High channel separation  
- No external components required for mute function  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

TV-sound demodulator circuit with SCART switches and AF control

Alternative Part Number

  • TDA3810 --: Same TDA38xx series audio processing IC with similar function and pinout, widely used as a direct substitute in audio applications.
  • LM1036N --: Popular tone/volume control IC offering comparable audio processing functionality and commonly used as a cross-reference replacement.
  • TDA1524A --: Audio tone and volume control IC from a different series with similar functionality, suitable as a functional alternative.
  • TDA3803A --: Philips TDA38xx series audio processor with comparable supply voltage and signal path; suitable functional replacement with minor pin check.
  • LA7222 --: Alternative audio processing IC from a different series offering similar TV sound functions; requires pinout verification but is a feasible cross-vendor option.
