IRS2092STRPBF

IRS2092STRPBF is a high voltage, high performance, protected digital audio amplifier driver with PWM modulator and protection. In conjunction with two external MOSFET and a few external components, a complete Class D audio amplifier with protection can be realized. International Rectifier’s proprietary noise isolation technology allows high current gate drive stage and high-speed low noise error amplifier reside on a single small silicon die. Open elements of PWM modulator section allow flexible PWM topology implementation. Typical applications include home theatre systems, mini-component stereo systems, powered speaker systems, and general purpose audio power amplifiers.
