TDA7480 is a class D audio amplifier manufactured by STMicroelectronics (ST).

The TDA7480 is a class D audio amplifier manufactured by STMicroelectronics (ST). Here are the factual details from the Manufactor Datasheet:

Specifications:

  • Output Power:
  • 20W per channel (stereo) into 4Ω at 10% THD with a 14.4V supply.
  • 10W per channel (stereo) into 8Ω at 10% THD with a 14.4V supply.
  • Supply Voltage Range: 8V to 18V (DC).
  • Efficiency: >90% (typical).
  • THD+N (Total Harmonic Distortion + Noise): <1% (typical).
  • Signal-to-Noise Ratio (SNR): >70dB.
  • Operating Frequency: Fixed-frequency PWM modulation (~300kHz).
  • Package: PowerDIP20 or SO20 (depending on variant).

Descriptions:

  • The TDA7480 is a monolithic integrated class D amplifier designed for high-efficiency audio applications.
