International Rectifier has launched its IRS2052M 2-Channel Class D Audio IC for high performance home theatre ­systems and car audio amplifiers. The new 200 V device integrates two channels into a single IC. Features include selectable dead-time and programmable bi-directional over-current protection, integrated clock oscillator and click-less start and stop.

“IR has already demonstrated that its single channel IRS2092(S), 3-channel IRS2053M and 4-channel IRS2093M Class D audio amplifiers offer equivalent sound quality to Class AB amplifiers while providing the additional benefits of higher efficiency and smaller size. The new IRS2052M, which integrates two channels onto one IC, provides the flexibility and convenience of building popular stereo amplifiers and multi channel designs in a 2.1ch, 5.1ch or 6ch configuration,” said Jun Honda, Director of audio systems ­engineering, Energy Saving Products Business Unit.

The device is optimised to work with the company’s range of digital audio MOSFETs, addressing output power from 50W to 300W to reduce component count and PCB space while achieving improved ­performance, efficiency, THD and EMI.

The devices are MSL2 Industrial ­qualified and RoHS compliant.
