Application Scenarios & Design Considerations

AF Power Amplifier (Split Power Supply) (20 W min, THD = 0.4%)

Alternative Part Number

  • STK4036II --: Same STK4000-series thick-film hybrid audio power amplifier family with comparable supply voltage and output power, widely used as a drop-in substitute for STK4024II in audio equipment.
  • STK4040II --: Higher-power member of the same STK hybrid audio amplifier series with identical pinout and package style, suitable when slightly more output headroom is acceptable.
  • TDA7294 --: Popular monolithic Class-AB audio power amplifier IC with similar output power range and supply requirements, commonly used as a functional replacement in audio amplifier designs.
  • STK4024V --: Later V-series version of the same 2-channel audio power amplifier family, offering equivalent function and improved reliability while fitting the same package footprint.
  • LM3886TF --: Widely available alternative class-AB audio power amplifier IC with comparable output power and supply range, suitable for redesigns where the original Sanyo part is obsolete.
