The TDA8953 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 x 210 W into a 4 Ω load in a stereo Single-Ended (SE) application, or 1 x 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.
