TFA9815 Stereo full-bridge audio amplifier

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-osc.
