描述 Description

Overview 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-oscillating digital audio amplifier system or open-loop system can be built. The continuous output power is 2 x17 W in a full-bridge BTL application. The TFA9815 does not require a heat sink and operates using an asymmetrical supply voltage.
