General description The TDA8921 is an high efficiency class-D audio power amplifier system. Typical output power is 2 x 50 W and it operates with high efficiency and very low dissipation. The devices comes in a HSOP24 power package with a small internal heatsink. No external heatsink is required, or depending on supply voltage and load a very small one. The system operates over a wide supply voltage range from +15 up to =+30 V and consumes a very low quiescent current. 2.
