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
n Stereo full-bridge power comparator for class D audio amplifier applications
n No external heat sink required
n Operating voltage range: asymmetrical from 8 V to 20 V
n Thermally protected
n Zero dead-time switching
n Current-limiting (no audible interruptions)
3. Applications
n Self-oscillating or open-loop class D audio amplifier applications
n Flat-panel television sets
n Flat-panel monitors
n Multimedia systems
n Wireless speakers
n High-end CRT television sets
TFA9810
Stereo full-bridge audio amplifier 2 x 12 W
