An integrated 200-W class-D audio amplifier.

An integrated stereo class-D audio power amplifier realized in a silicon-on-insulator (SOI)-based BCD technology is presented. The amplifier is capable of delivering 2×100 W in two 4-Ω loads at a supply voltage of 60 V. A second-order feedback loop is used to suppress supply ripple and pulse-shape e...
