General description: The TDA8954 is a stereo or mono high-efficiency Class D audio power amplifier in a   single IC featuring low power dissipation. It is designed to deliver up to 2 × 210 W into a  4 Ω load in a stereo Single-Ended (SE) application, or 1 × 420 W into an 8 Ω load in a  mono Bridge-Tied Load (BTL) application.  It combines the benefits of Class D efficiency (≈93 % into a 4 Ω load) with audiophile  sound quality comparable to that associated with Class AB amplification.  The amplifier operates over a wide supply voltage range from ±12.5 V to ±42.5 V and   features low quiescent current consumption.  The TDA8954 is supplied with two diagnostic pins for monitoring the status of Thermal   Fold Back (TFB), Over Current Protection (OCP) and other protection circuits. Features: „ High output power in typical applications: ‹ SE 2 × 210 W, RL = 4 Ω (VDD = 41 V; VSS = −41 V) ‹ SE 2 × 235 W, RL = 3 Ω (VDD = 39 V; VSS = −3...

This system only requires a simple passive LC demodulation filter to deliver high-quality, high-efficiency audio amplification with proven EMI compliance. 2 x 210 Watt STEREO DIGITAL AMPLIFIER POWER STAGE
