Application Scenarios & Design Considerations

PLL stereo decoder

Alternative Part Number

  • TDA7050 --: Low-voltage audio amplifier IC in the same application class; NXP (formerly Philips) is the direct successor brand, making it a reliable drop-in candidate after pinout verification.
  • LM386 --: Widely available general-purpose low-voltage audio amplifier with similar supply range and output power; a common substitute for small audio driver stages.
  • TDA2822M --: Dual low-voltage audio power amplifier commonly used in similar consumer audio circuits; good availability and comparable electrical characteristics.
