MAX9714

19-3039; Rev 2; 9/04 6W, Filterless, Spread-Spectrum Mono/Stereo Class D Amplifiers 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 patent-protected modulation and switching schemes render the traditional class D output filter unnecessary. www.DataSheet4U.com 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 100dB. 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.
