Application Scenarios & Design Considerations

100+100W STEREO BASH POWER AMPLIFIER

Alternative Part Number

  • TDA7560 --: Quad BTL car audio power amplifier in the same class as the STA575, with comparable output power and supply voltage range, widely used as a direct substitute in car radio designs.
  • TDA7850 --: Higher-power quad BTL amplifier with similar pinout and supply requirements, commonly used to replace STA-series devices in automotive audio applications.
  • TDA7388 --: Quad BTL car audio amplifier with compatible supply voltage and output topology, a cost-effective fallback alternative when the STA575 is unavailable.
