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 × 210W into a 4Ω load in a stereo Single-Ended (SE) application, or 1 × 420W into an 8Ω 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 ±12.5V to ±42.5V and features low quiescent current consumption.The TDA8954 is supplied with two diagnostic pins for monitoring the status of Thermal Fold Back (TFB), Overcurrent Protection (OCP) and other protection circuits
