Stereo full-bridge audio amplifier 2 x 17 W
Rev. 01 -- 16 December 2008 Preliminary data sheet
1. General description
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 17 W in a full-bridge BTL application. The TFA9815 does not require a heat sink and operates using an asymmetrical supply voltage.
