Application Scenarios & Design Considerations

Sound Terminal 2-channel microless high-efficiency digital audio system

Alternative Part Number

  • TDA7491LP --: Similar class-D audio amplifier in the same power range with comparable supply voltage and output capability, suitable as a functional substitute.
  • TAS5751M --: Class-D audio amplifier IC from a different vendor offering comparable output power and digital input options, usable as a cross-vendor alternative.
  • MAX98357A --: Digital-input class-D amplifier with integrated DAC, providing a different-series alternative for low-to-mid power audio amplification applications.
  • TAS5711PHPR --: Class-D audio amplifier with integrated DSP and I2S input, functionally similar to the STA333ML and widely available as a drop-in class alternative.
  • TDA7492P --: Same manufacturer's Class-D audio power amplifier family, comparable output power and analog input architecture, suitable when DSP features are not required.
  • MAX98357AETE+T --: Digital-input Class-D amplifier with I2S interface, good substitute for low-power digital audio designs when the STA333ML is unavailable.
