TFA9810
Datasheet
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.
Features
- 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)
