General Description

The MAX9703/MAX9704 mono/stereo Class D audio power amplifiers provide Class AB amplifier performance with Class D efficiency, conserving board space and eliminating the need for a bulky heatsink.

Using a Class D architecture, these devices deliver up to 15W while offering up to 78% efficiency.

Proprietary and patent-protected modulation and switching schemes render the traditional Class D output filter unnecessary.
