TFA9810  
Stereo full-bridge audio amplifier 2 x 12 W  
Rev. 03 — 20 February 2008  
Product data sheet  
1. General description  
The TFA9810 is a two-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 amplifier system or open-loop  
system can be built. The TFA9810 does not require a heat sink and operates using an  
asymmetrical supply voltage.  
2. Features  
I Stereo full-bridge power comparator for class D audio amplifier 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
