TFA9815 Datasheet (NXP Semiconductors) - Stereo full-bridge audio amplifier

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
