These MOSFETs, have been optimized around parameters critical to audio performance such as efficiency, THD, and EMI. For detailed performance information, please refer to the MOSFET data sheets available online at www.irf.com. The chipset forms a Class D audio solution that is much smaller than a comparable Class AB design. In a 100W application, for example, the IRS2053 IC and IRF6665 DirectFET® MOSFETs reduce board size by 50% to the previous offerings.
