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 I I I I I Stereo full-bridge power comparator for class D audio amplifier applications No external heat sink required Operating voltage range: asymmetrical from 8 V to 20 V Thermally protected Zero dead-time switching Current-limiting (no audible interruptions) 3. Applications
