General Description
The MAX9741 stereo Class D audio power amplifier provides Class AB amplifier performance with Class D efficiency, conserving board space and eliminating the need for a bulky heatsink. Using a high-efficiency Class D architecture, it delivers 12W continuous output power into 8Ω loads. Proprietary modulation and switching schemes render the traditional Class D EMI suppression output filter unnecessary.
