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.
