The MAX9704ETJ+ is a 10W stereo, filterless, spread spectrum, class D amplifier in 32 pin TQFN package. The mono/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. The protected modulation and switching schemes render the traditional class D output filter unnecessary. The MAX9704 offers two modulation schemes, a fixed frequency mode (FFM) and a spread spectrum mode (SSM) that reduces EMI-radiated emissions due to the modulation frequency. The device utilizes a fully differential architecture, a full bridged output and comprehensive click and pop suppression.

• Supply voltage range is 10V to 25V
• Operating temperature range from -40°C to 85°C
• Unique spread spectrum mode offers 5dB emissions improvement over conventional methods
• Up to 78% efficient (RL = 8ohm) and up to 88% efficient (RL = 16ohm)
• 2x10W continuous output power into 8ohm
• Low THD+N of 0.07%
• High PSRR of 80dB at 1KHz and SNR in excess of 95dB
• Short circuit and thermal overload protection
• Low quiescent current of 24mA and low power shutdown mode reduces supply current to 0.2μA
• Differential inputs minimize common-mode noise
