Part Details:

19-3160; Rev 7; 3/06 10W Stereo/15W Mono, Filterless, Spread-Spectrum, Class D Amplifiers MAX9703/MAX9704 General Description Features The MAX9703/MAX9704 mono/stereo Class D audio Filterless Class D Amplifier power amplifiers provide Class AB amplifier performance Unique Spread-Spectrum Mode Offers 5dB with Class D efficiency, conserving board space and Emissions Improvement Over Conventional eliminating the need for a bulky heatsink. Using a Class Methods D architecture, these devices deliver up to 15W while Up to 78% Efficient (RL = 8) offering up to 78% efficiency. Proprietary and patent-pro- Up to 88% Efficient (R tected modulation and switching schemes render the tra- L = 16) ditional Class D output filter unnecessary. 15W Continuous Output Power into 8 (MAX9703) The MAX9703/MAX9704 offer two modulation schemes: 2x10W Continuous Output Power into 8 (MAX9704) a fixed-frequency mode (FFM), and a spread-spectrum Low 0.07% THD+N mode (SSM) that reduces EMI-radiated emissions due High PSRR (80dB at 1kHz) to the modulation frequency. The device utilizes a fully 10V to 25V Single-Supply Operation differential architecture, a full bridged output, and com-prehensive click-and-pop suppression. Differential Inputs Minimize Common-Mode Noise The MAX9703/MAX9704 feature high 80dB PSRR, low Pin-Selectable Gain Reduces Component Count 0.07% THD+N, and SNR in excess of 95dB. Short-cir- Industry-Leading Click-and-Pop Suppression cuit and thermal-overload protection prevent the Low Quiescent Current (24mA) devices from being damaged during a fault condition. Low-Power Shutdown Mode (0.2µA) The MAX9703 is available in a 32-pin TQFN (5mm x5mm x 0.8mm) package. The MAX9704 is available in a Short-Circuit and Thermal-Overload Protection 32-pin TQFN (7mm x 7mm x 0.8mm) package. Both Available in Thermally Efficient, Space-Saving devices are specified over the extended -40°C to Packages +85°C temperature range. 32-Pin TQFN (5mm x 5mm x 0.8mm)­MAX970332-Pin TQFN (7mm x 7mm x 0.8mm)­MAX9704 Applications Ordering Information LCD TVs Hands-Free Car PART PIN-PACKAGE AMP
