6W, Filterless, Spread-Spectrum Mono/Stereo Class D Amplifiers

6W, Class-D Amplifiers Ideal for Flat-Panel TV and PC Display Applications

Please check latest availability status for a specific part variant.


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. Modulation and switching schemes render the traditional Class D output filter unnecessary.

The MAX9713/MAX9714 offer 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.

The MAX9713/MAX9714 feature high 76dB PSRR, low 0.07% THD+N, and SNR in excess of 95dB. Short-circuit and thermal-overload protection prevent the devices from being damaged during a fault condition. The MAX9713 is available in a 32-pin TQFN (5mm x 5mm x 0.8mm) package. The MAX9714 is available in a 32-pin TQFN (7mm x 7mm x 0.8mm) package. Both devices are specified over the extended -40°C to +85°C temperature range.
