3channel Class D audio driver IC delivers ‘superior sound quality in a smaller footprint’

Based on a Class D audio amplifier topology, the IRS2053M integrates three channels of high voltage, high performance half bridge drivers with PWM modulators. The new device's comprehensive set of protection features includes programmable bi-directional current sensing to protect high and low side mosfets from over current conditions. Other key features include logic compatible input and floating PWM input. According to the company, the IRS2053M offers a Class D Audio solution with excellent sound quality, delivering a smaller footprint and higher power compared to alternative solutions when combined with IR's high efficiency power mosfets. When co-designed with the single channel IRS2092(S) and four channel IRS2093M, the IRS2053M offers the flexibility to configure 2.1, 6 and 6.1channel applications. IR's extensive range of digital audio mosfets addressing output power from 50W to 150W, are optimised for the IRS2053M to reduce component count and pcb space while achieving improved performance, efficiency, THD and EMI. A datasheet and application note are available on the International Rectifier website at http://www.irf.com. In addition, the IRAUDAMP11 Reference Design featuring the IRS2053M is also available. Production quantities are available immediately. The devices are MSL2 Industrial qualified and RoHS compliant.
