General Description

The MAX9713/MAX9714 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 6W while offering greater than 85 efficiency. Proprietary and protected modulation and switching schemes render the traditional Class D output filter unnecessary.
