International Rectifier Intros IR2011 MOSFET Driver IC

International Rectifier Corp. (IR, El Segundo, CA) introduced the IR2011 high-side and low-side MOSFET driver IC for 100 W to 1,000 W Class D audio amplifier circuits. The new 200 V driver device has a maximum ambient temperature rating of 125 °C. Applications for Class D amplifiers range from battery-powered portable products to high-end professional amplifiers, musical instruments, and car and home multimedia systems.

The new device has matched propagation delay on both channels to simplify high-frequency circuits needed for optimum total harmonic distortion response. Logic inputs are compatible with CMOS or LSTTL output to 3 V without any speed degradation.

The new IR2011 Class D audio driver IC is available now. Pricing is $1.25 each for the IR2011 in the eight-pin DIP and $1.30 each for the IR2011S in the SO-8 package, both in 10,000-unit quantities. The IR2011 is also available in a lead-free package.
