TAS5825P - High Efficiency Closed-Loop Class-D Audio Amplifier

Description

TAS5825P is a stereo high-efficiency Closed-Loop audio Class-D audio amplifier with an advanced Hybrid-Pro algorithm to improve system efficiency and reduce heat without clipping distortion.

The supply voltage (PVDD) of an audio amplifier is normally provided by a DC-DC converter.

Features

  • High-efficiency Class-D operation with Hybrid-Pro:.
  • Approximately 50% longer battery life compared to fixed supply voltage solutions.
  • > 90% Power efficiency, 90 mΩ RDS(on).
  • Low quiescent current, < 20 mA at 12 V PVDD.
  • Supports multiple output configurations:.
  • 1 × 53 W, 1.0 Mode (4-Ω, 22 V, THD+N=1%).
  • 1 × 65 W, 1.0 Mode (4-Ω, 22 V, THD+N=10%).
  • 2 × 30 W, 2.0 Mode (8-Ω, 24 V, THD+N=1%).
  • 2 × 38 W, 2.0 Mode (8-Ω, 24 V,.
