TDA8953  
2 × 210 W class-D power amplifier  
Rev. 01 — 24 December 2009  
Product data sheet  
1. General description  
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 × 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.  
2. 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 = 39 V)  
‹ SE 2 × 150 W, RL = 6 Ω (VDD = 41 V; VSS = 41 V)  
‹ BTL 1 × 420 W, RL = 8 Ω (VDD = 41 V; VSS = 41 V)  
„ Symmetrical operating supply voltage range from ±12.5 V to ±42.5 V  
„ Stereo full differential inputs, can be used as stereo SE or mono BTL amplifier  
„ Low noise  
„ Smooth pop noise-free start-up and switch off  
„ Fixed frequency internal or external clock  
„ High efficiency 93 %  
„ Zero dead time switching  
„ Low quiescent current  
„ Advanced protection strategy: voltage protection and output current limiting  
„ Thermal FoldBack (TFB) with disable functionality  
„ Fixed gain of 30 dB in SE and 36 dB in BTL applications  
„ Fully short-circuit proof across load  
„ BD modulation in BTL configuration  
„ Clock protection
