TFA9815  
Stereo full-bridge audio amplifier 2 x 17 W  
Rev. 01 — 16 December 2008  
Preliminary data sheet  
1. General description  
The TFA9815 is a 2-channel power comparator for high-efficiency class D audio amplifier  
systems. It contains two full-bridge Bridge-Tied Load (BTL) power stages, drive logic,  
protection control logic and full differential input comparators. By using this power  
comparator a compact closed-loop self-oscillating digital audio amplifier system or  
open-loop system can be built. The continuous output power is 2 ×17 W in a full-bridge  
BTL application. The TFA9815 does not require a heat sink and operates using an  
asymmetrical supply voltage.  
2. Features  
I Stereo full-bridge audio amplifier for class D applications  
I No external heat sink required  
I Operating voltage range: asymmetrical from 8 V to 20 V  
I Thermally protected  
I Zero dead-time switching  
I Current-limiting (no audible interruptions)  
3. Applications  
I Self-oscillating or open-loop class D audio amplifier applications  
I Flat-panel television sets  
I Flat-panel monitors  
I Multimedia systems  
I Wireless speakers  
I High-end CRT television sets
