Application Scenarios & Design Considerations

FOCUS OUTPUT POWER AMP

Alternative Part Number

  • STK4241V --: Same STK42xx thick-film hybrid audio power amplifier family with comparable output power and pinout, widely used as a drop-in substitute in audio equipment.
  • STK4256 --: Similar dual-channel hybrid audio power amplifier in the STK42xx series with matching supply voltage range and package style, suitable for equivalent audio output stages.
  • LM3886TF --: Modern monolithic Class-AB audio power amplifier offering comparable output power and performance, commonly used to replace obsolete STK hybrid modules with minor circuit adaptation.
  • TDA7294 --: Popular DMOS audio power amplifier IC with comparable output power and voltage ratings, widely used as a functional alternative when the original hybrid module is unavailable, though pinout and circuit adaptation are required.
  • LM3886 --: Popular discrete-module alternative audio power amplifier IC with comparable output power and voltage range; requires minor circuit adaptation but is a reliable modern replacement.
