Application Scenarios & Design Considerations

Digital Amplifier Power Stage

Alternative Part Number

  • TAS5142DDV --: Same TAS51xx PurePath digital amplifier family with comparable output power and PWM input, in a different package, making it a strong functional substitute.
  • TAS5121DKD --: Similar TAS51xx class-D digital audio amplifier with comparable power rating and digital input interface, suitable as a drop-in functional alternative.
  • TAS5707PHP --: TI digital audio amplifier with integrated DSP and similar PWM output stage, usable as an alternative when minor pin and configuration differences are acceptable.
