Application Scenarios & Design Considerations

Digital Amplifier Stereo Power Stage

Alternative Part Number

  • TAS5122DCA --: Same TAS51xx class-D amplifier family with comparable output power and supply range, in a different package, suitable as a functional substitute.
  • TAS5142DDV --: Higher-power TAS51xx family member with similar PWM input interface and control scheme, usable where extra headroom is acceptable.
  • TAS5612LADDVR --: Later-generation TI class-D amplifier with similar audio input and power-stage architecture, offering a modern alternative with improved efficiency.
  • TAS5112ADFD --: Same TAS5112 amplifier family in the same DFD power package, with closely matching pinout and electrical ratings, making it a near drop-in replacement.
  • TAS5122DFD --: Sister device in the TAS51xx class-D amplifier series with comparable output power and supply range, suitable for similar audio applications.
  • TAS5142DFD --: Higher-power member of the same TAS51xx family in the same package style; usable as an alternative where slightly greater output capability is acceptable.
