Application Scenarios & Design Considerations

2 x 1.4 W BTL audio amplifiers with digital volume control and headphone sensing

Alternative Part Number

  • LM4863MTE --: Dual 2W class-AB audio amplifier in a similar power range with comparable supply voltage and gain configuration, suitable as a functional substitute for the TDA8552TS in audio output stages.
  • PAM8403 --: Low-cost 3W dual class-D audio amplifier that can replace the TDA8552TS in many small audio applications, offering higher efficiency and similar supply voltage range.
  • STA540 --: Multiwatt audio amplifier IC with comparable output power and supply range, usable as an alternative when the TDA8552TS is unavailable, though package and pinout differ and require layout adjustment.
